Suggested January 2024 Drone Diary: Shooting A Dance Video Really Demonstrated The Value Of A Flying Camera
Unusually for me, there aren’t many words in this drone diary – mostly I’m going to let the video do the talking!
When I reviewed the Litchi app last time – an app that lets the drone fly completely autonomously on a pre-programmed path – I mentioned a plan I had in mind for a future project at that tumbledown castle.
The plan was to take a dancer there and shoot a dance routine from the air in a beautiful setting. This required the cooperation of the weather, but it all came together earlier this month. It was a lot of fun, and I think the result really shows the value of a video camera you’re able to position exactly where you want it – whether up high or down low …
Part of what drones have going for them, of course, is that they offer a vantage point not possible with a conventional camera. At this stage – when decent drones are still expensive enough to remain a relative rarity – there’s a wow factor to being able to shoot from the air.
But what I discovered on this shoot is that even when you want to shoot from more-or-less ground level, a drone takes the place of a lot of expensive kit and a skilled operator. Smooth tracked shots, for example, are traditionally done with either a dolly or a crane. Both very expensive pieces of kit requiring multiple people to transport and set them up, and a skilled operator to use them. A drone coupled to the Litchi app gets you the same result in a relatively inexpensive and highly portable package.
I did shoot some of the video from up high, including a couple of overhead shots.
But other shots were taken as low as the drone would go when flying autonomously – which was 16 feet. If I could have gone lower, I would have done. The value of the drone in these shots was its ability to emulate expensive movie-making kit rather than, specifically, the fact that it could fly.
I open the video by tracking a curved path around a tower, revealing the dancer within. You may recall me showing how I used Litchi to create the flight-path for this shot.
Here’s a still from that part of the video.
Of course, there is one thing professional film-makers have going for them: the budget to hire venues for their exclusive use. I wasn’t able to do that, so you’ll see some people in the background, but I must say that those there were super helpful in aiming to stay out of our way.
Litchi behaved flawlessly. The preprogrammed paths I created were all done on Google Earth from the comfort of my own home, and for the most part I was able to use them as-is. The only modification I had to make on the day– altering the centre point of the circles it flew – was to take into account the uneven surface of the ground, to give the dancer a flattish dance floor.
Ok, that’s enough words: here’s the video.
Many thanks to Monika Szpunar for her amazing dance work, and to Kevin MacLeod for the beautiful music.

You're reading Drone Diary: Shooting A Dance Video Really Demonstrated The Value Of A Flying Camera
So you’ve just purchased a shiny new drone. As soon as you register your high-tech device (required for fliers that weight anything from 0.55 to 55 pounds, which most consumer UAVs do), you’ll be ready to take to the skies. But wait—what if you crash and destroy your drone on its first outing? We’ve collected safe-flying tips from manufacturers and the Federal Aviation Administration, so you can avoid injuring bystanders or, more important, harming your expensive gadget itself.Start slow
Once the drone’s features seem familiar, try a low-key first flight: Hover a few feet off the ground in an obstacle-free space like your backyard. This will give you an opportunity to become comfortable with the controls and settings before you head out to a more populated, distracting area like a public park.
Even if you’re eager to push the limits of your new toy, resist the temptation to do too much too soon. Although many of today’s drones include beginner-friendly features, such as avoiding obstacles and hovering in place on their own, you should learn how to perform these tasks yourself. If you’re still uncomfortable with the device after reading the instructions and taking a low test flight, then check out a beginner’s course: DJI, for example, runs occasional free classes.Perform maintenance checks
Even after you become comfortable with the controls, you should take time before each flight to run a quick set of maintenance checks. Think of it like servicing a car before you the road, a necessary precaution to avoid future damage.
First, make sure to charge the main battery, as well as any spares you plan to carry. Next, look at all the device’s propellers: Check all of them for signs of wear and tear and, if they seem loose, securely fix them in place.
If your drone includes a compass, your final step will be to calibrate this instrument. Because locations can have unique electromagnetic profiles, the signals in one area may not match those in another. A compass calibration before flight will tell the drone exactly where it is—allowing you to position it accurately—once it’s in midair. You should find this process as an option in the app affiliated with your drone.Keep the drone in view
You should also stay in control of the drone at all times. Keep your hands on the steering, even when the drone’s in automatic takeoff or landing mode. Another way to stay aware of the drone’s orientation is to get in the habit of starting each flight with the drone, and its camera, facing you.
To avoid losing control, the FAA also recommends that you don’t fly while under the influence of drugs or alcohol. If you’re too sloshed to get behind the wheel of a car, then don’t pick up your drone, or you could end up with hundreds of dollars worth of broken gear.Stick to wide open spaces
You need a lot of space to fly a drone, so restrict your flights to wide open spaces like parks and the countryside. These locales are also ideal for keeping your drone in view—you won’t be surprised by trees or billboards.
As the flip side of that, the FAA recommends steering clear of people, buildings, and the crowded areas you’ll find at public events. This will help protect not only your drone, but also other people. As a bonus, avoiding fellow humans means you’ll avoid situations where a neighbor might accuse you of surveillance.
In addition to people, you want to keep your drone away from animals. If the buzzing UAV spooks them, they can react unpredictably, sometimes going so far as attacking and destroying your gadget. Wooded areas and barns can hide wild or domestic animals, so err on the side of caution and don’t disturb habitats like these.Avoid no-fly areas
Not even drones can roam everywhere in the sky. The FAA limits the maximum altitude you can explore, and restricts drones within certain no-fly zones. These rules aim to protect your drone from damaging itself or others.
Recreational drones must not fly higher than 400 feet into the air. Even at that restricted height, you might encounter other aircraft: Emergency responders, agricultural workers, and others can fly at low altitudes, and in places you wouldn’t expect. So obey the altitude limit, and keep your eyes and ears open while you’re aloft.
In addition, you shouldn’t fly within five miles of an airport or airfield, for obvious reasons: If your drone smacks into a passenger jet, then it’s probably game over for your flying machine. Of course, this can cause problems for the larger aircraft too.
Drones are also banned from the area around Washington DC, anywhere near an active wildfire, and other locations. For a full list of flight-restricted areas, check out the FAA’s website. Before you take you drone to a new location, make sure the site is far from flight paths, landing strips, and other verboten areas. And stay low.
So, you’ve just earned a sweet backlink from a website.
Now what? Is it really valuable enough to see changes to your authority and rankings?
We’ve been told time and time and time again that links are critical to search engine ranking.
But not all links are created equal. Some can even damage your site at scale.
There are tons of factors that determine the real value of a backlink. Factors that let you know the link you just earned is Grade-A.
In this piece, I’ll run through some of (not all) these factors to help you determine the value of your backlinks.1. Unique Root Domains or Total Backlinks?
After earning your latest link, the first metric you should check is whether that link was from a unique root domain or not.
A unique root domain means the link you just received was from a website that hasn’t linked to your site previously:
And that’s super valuable.
Think of each backlink to your website as a testimonial, and Google is viewing your site deciding whether or not to buy (read: rank).
If Google looks at your website and notices you have 15 testimonials from the same person (read: root domain), it’s far less convincing than 15 testimonials from 15 different people.
In fact, it might be a little suspicious if your link profile is small yet filled with links from the same source. Diversification is key.
94% of all content online has zero backlinks.
So a few backlinks from the same root domain isn’t going to hurt you.
But if it’s all you’ve got, it’s a sign you need to step up your own outreach and start becoming proactive about link building to diversify your profile.
The more relevant unique domains you can earn links from, the better.2. Domain Rating / Domain Authority – Vanity Metric?
Domain Rating (a term via Ahrefs), Domain Authority (a term via Moz), Authority Score (a term via SEMrush).
While named separately, they are essentially calculations of the same thing:
An overall score from 0-100 calculated by multiple factors, mainly total backlinks, unique backlinks, and the relative authority of each of those backlinks.
In plain English: if a domain rating is high, the site has lots of great links from lots of great sites. If a domain rating is low, the site has fewer links from fewer unique sites.
Is it a vanity metric?
To an extent, yes.
So, does it matter?
Look at any SERP for any competitive keyword and tell me otherwise:
Almost everyone ranking for “international SEO” has a DR above 90.
Domain rating is more than just a vanity calculation.
While not used directly by Google, it’s a clear indication of what these tools believe Google trusts: sites with healthy, diverse backlink profiles that are creating amazing content.
In other words: authoritative sites that people are constantly talking about, trusting, and sourcing.
Earning a link from a huge site with a domain rating of 90+ can be a massive boost to your own site’s DR and trust signals.
Speaking from years of experience in link building for hundreds of clients in all niches, non-spammy links over 50 in Ahrefs Domain Rating can have a significant impact on your own authority and trust.
But, DA/DR/AS are not the end-all-be-all metric.
Don’t be discouraged if you acquire a link from a site with a domain rating of 55 rather than a coveted 90.
You’d be pleasantly surprised how strong a DR55 site can be.
Strong enough to outrank Alexa, SEMrush, and even Search Engine Journal if the content is good enough.3. Spam Scores: How High Is Too High?
Spam Score, coined by Moz, represents “the percentage of sites with similar features we’ve found to be penalized or banned by Google.”
Spam scores and link building are often discussed, and it’s quite common to hear that high spam scores = your website is going to get penalized ASAP.
Unfortunately, that’s not super accurate.
Straight from the mouth of Moz:
“Well established links, even with a higher Spam Score, can still add value and authority to your site.”
While having an entire link profile of insanely spammy sites is clearly bad, having some sites with high spam scores isn’t.
The guidelines set by Moz are:
1-30% = Low
31-60% = Medium
61-100% = High
Generally speaking, you will almost always have a mix between these scores.
For link optimization purposes, your link profile should skew towards majority low, some medium, and few high.
High spam scores don’t instantly mean you should disavow. Instead, take it on a case-by-case basis.
Ask yourself a few questions when looking at a link with a higher spam score:
Is this website legit? Or is it a shady PBN that is spam building links?
Is the piece of content I am mentioned within good? Or is it jammed with exact match anchors from hundreds of sites?
Is the anchor text contextually relevant, or is this a big directory of random links?
It’s easy to tell if an outbound link is spammy. And the surface level of spam scores can’t always tell you.4. Organic Traffic: Does It Matter?
When trying to discern the value of a backlink you just acquired, organic traffic is a good metric to explore.
Depending on what source you use (Ahrefs, SEMrush, SimilarWeb, etc.), you’ll find a whole range of organic traffic estimations.
Using a tool like Ahrefs, it’s quite easy to tell if a site is getting good organic traffic:
If the keywords are high volume and they are ranking high on the first page, they likely have some great organic visitors each month.
Generally speaking, you want to acquire links from sites with steady, high rates of organic traffic.
Anything over 1,000 in organic traffic is a great starting point. And obviously, anything higher is even better.
Organic traffic to a page you are linked on isn’t directly going to improve your keyword rankings.
But it surely will drive organic referral traffic to your website, and that’s a huge potential for indirect ranking boosts from new links, shares, and engagement.5. Anchor Text: Is Exact Match Harmful?
One of the biggest questions I see in the link building space surrounds anchor text.
Half of the crowd wants exact match anchors to boost keyword rankings.
The other half wants “natural” anchors to avoid Google penalties.
So, who is right?
Both are. Link building is rarely one or the other. It’s rarely about getting all DR90 links, and more about having a balance.
When you overdo anything on one spectrum or the other, it’s not natural.
If you are a tiny site with one blog post acquiring 100 links with an exact match anchor, something is suspicious.
On the contrary, if you acquired 100 links from a study you developed and the anchors vary from image citations, statistic citations, quotes from the article, exact matches, and more, that’s fantastic.
That’s a sign that these links were earned and built naturally, not acquired by any artificial method of gaming the system.
When it comes to a natural-looking link profile, shoot for both exact match anchors and more “natural” anchors of image citations, quotes, homepage links, and more.6. Competitor Analysis: Creating a Backlink Gap
Backlinks that you get that your competitors don’t have are extremely valuable for multiple reasons:
It drives trust signals and authority to you only in your niche, rather than a whole host of competitors benefiting.
You drive more direct referral traffic than your competitors.
Each subsequent link that you get drives up authority, separating you from competitors.
Each time you acquire a link, throw your domain into a Link Intersect report:
This shows you who is linking to you and not your competition, or visa versa.
If the root domain is linking to you and not your competition, the value of the link is higher (all things considered).
If they are linking to your competition too, that’s still a huge win. Why? You closed the backlink gap that your competitor had on you.
With each link you acquire and each outreach email you send, seek to create a larger backlink gap that improves your domain authority over your competition.7. Mention Context Is Critical
All of the factors I just mentioned above are important.
But, the mention context is critical.
By mention context, I simply mean: assess all the factors around your link to see if the context is relevant and impactful.
In other words…
How well-written is the article you were mentioned in?
Is it a 500-word piece that will never rank? Or is it a 5,000-word ultimate guide toppling giants on the SERPs?
Was the topic you were mentioned in directly related to your backlink? Or was the keyword anchor stuffed and out of place?
Were you linked amongst 150 other people, or in a select group of a few other outbound links?
Was the content shared to a social network driving direct engagement and compounding links?
I could go on and on.
The context is key. If you are getting mentions on crappy articles from crappy sites with crappy context, it’s far less valuable.
Take a hard look at the article that mentioned your brand or linked to your site. If the article is great, topically relevant, and interesting, you’ve acquired a dynamite link.Conclusion
When you acquire a new backlink, checking its value is the first thing you should do.
Assess unique root domains, domain rating, spam scores, organic traffic, anchor text, and the mention context.
While there are more factors, these are some of the most important.
Almost all links are valuable to your overall profile, but some are more valuable than others.

Snapchat is one of the most popular social media platforms in today’s day and age. From a humble service that allowed you to send timed messages, Snapchat has slowly grown into a multi-dimensional social media platform. The modern-day app allows you to post stories, add filters, create episodes, and post all kinds of different content on the platform. And with TikTok at the risk of getting banned from most countries, Snapchat is now looking to capitalize and pull users onto their platform. How do they plan to do this? With new Snapchat lenses of course! Let’s take a look at them.
What are the new Snapchat dance challenge lenses?
The main reason for TikTok’s huge popularity is the ability to take part in viral dance challenges and get famous yourself. Many people use in-built audio tracks on TikTok to create their videos on popular songs. You can also duet alongside viral challenges to get better traffic to your profile. Snapchat is looking to bring the same functionality to its users via some new lenses.
The new viral dance challenge lenses are being released in conjunction with 4 famous TikTok stars, Jalaiah Harmon, Sarati, Loren Gray, and Dixie D’Amelio! Each star has got its own unique Snapchat lens that conforms to your body as you dance around. This way you can take part in viral dance challenges and leverage Snapchat lenses to create a more compelling video.
How do the new Snapchat full-body lenses work?
The new lenses by Snapchat track your body in real-time. The algorithm isolates 18 joints in your body and tracks filters according to their position in real-time. This helps give you a nice look without any glitches or bugs.
How to use new lenses?
The new 4 lenses released in collaboration with TikTok stars are now available within the Snapchat app. Follow the guide below to get you started.
Note: This guide applies to both iOS and Android users.
Open the Snapchat app on your mobile device and tap on the ‘Lenses’ icon beside the Shutter button.
Now tap on ‘Explore’ in the bottom right corner of your screen.
You should now see the 4 new lenses in the ‘For you’ tab of the screen. If the lenses are not available to you in this tab, you can use the search terms below to find them individually.
Tap on the lens you wish to use and Snapchat will automatically load the lens for you. You can now point the camera at your body and start recording your video.
Do the new lenses come with songs
A main selling point of TikTok was the ability to add music to your videos directly from the app itself. TikTok also gives you the ability to use tracks from existing and viral videos to join in on new trends and challenges.
While Snapchat does plan to offer users music from within the app, the feature will be released at the end of 2023. For now, only two of the lenses currently released feature music embedded into them.
The new lenses that you create in Lens Studio can also have music in them but as for third party music or using your music, there is no way to do that for now. You will have to use third-party apps to either add music to your videos or play it on a loudspeaker and record it on the video itself.
Can you make your own viral dance challenge lenses on Snapchat?
Yes, this is the main selling feature of these new lenses. Snapchat now offers you the ability to create your dance challenge lenses right out of the box. This allows you to create and add your graphics to create a completely new lens that suits your needs. This can come in especially handy if you are looking to stand out of the crowd using your creation. This also allows you to create something unique and your own. Simply head over to the Lens Studio and start making your creation today.
Note: You will need a decently specced Windows machine to make the most out of Lens Studio by Snapchat.
This year, we witnessed a continued and rapid acceleration of the relationship between content and SEO.
As consumers looked to find more relevant information to their questions online, search marketers strived to ensure the answers, and content, are relevant and visible.
Events like COVID-19 affected the demand for SEO and the need for high-quality, informational, and up to date content.
The way search engines have matured meant that marketers now have to put the creation of dynamic content to the top of their business SEO agendas.
Creating valuable content is a process, and its impact on SEO is sometimes misrepresented.
It’s one thing to haphazardly throw some words together and call it a blog post or an article.
It’s quite another to create content that has real SEO value for your company and is also received well by your target audience.
More quantity does not necessarily mean success.
With each additional layer of insightful content you add, more quality can help boost success via SEO value.Google & High-Quality Content
Quality of content can be a subjective topic for many.
While some may view high ranking and a large amount of traffic as a sign of quality, others may consider a specific type of engagement or particular action taken as a sign of success.
The end goal of any content you produce for SEO should always be on providing content that answers a user’s question.
Content that is relevant, useful, and authoritative.
Adhering to Google’s guideline and SEO best practices is a must.
However, this should not be done at the cost of optimizing for the user – what they want, their need, and their intent.
Ultimately, it’s their experience.
Finding the balance between optimizing for search engine results (technical and foundational SEO) and optimizing for the user is how the best marketers operate.
In a Google Webmaster Hangout, John Mueller was recently asked what quality content for Google meant.
His answer points to not focusing on what Google might algorithmically think is high quality and focusing on what users will respond to as high quality.
“So that’s something where I wouldn’t worry too much about what Google thinks about quality content. But rather you need to show that you really have something that’s unique and compelling and of high quality.”
After all, this is why major search algorithm updates, such as Google’s Panda and Penguin and innovations around RankBrain, and BERT, were all brought to the market.
To try and ensure search results match user intent.
The latter two looking at how AI machine learning can help interpret and serve better results by understanding human language.Measuring Content Value to SEO: From Rank to Revenue
Anyone who uses SEO to increase their organic search engine visibility and traffic should be measuring their results.
Because of the human role in content consumption and their effect on search engine rankings, it’s essential to ensure that your content satisfies both technical and human requirements.
There is a difference between what you measure between content and rank, and how you measure content revenue.
This post aims to give you a little more insight and a framework into how best to measure your content piece and its performance.Foundational Technical SEO Metrics
Often considered “technical” and foundational SEO metrics, organic rank and visibility give tremendous initial insight into how your content performs.
This can be done by looking at a combination of on or off-page metrics.
Keyword rankings: How and where your content shows up on the SERPs.
Traffic: How much traffic is being brought to the page your content is hosted on.
Backlinks: The number of inbound links pointing to your webpages.Website Engagement Metrics
This is a crucial area of measurement that shows where and how SEO and content combine.
No matter how good you think your website or content piece is, if people are not reading and digesting it, you have no way of measuring or improving expertise, authority, and trustworthiness.
Google refers to this as E-A-T.Conversion Rates
This could be from several sources, depending on where you have placed your content.
Direct: From people directly on your website/page.
Search: People who found your content on a search engine.
Referral: People who saw your content via a link from another source – another website, or social, for example.
When looking at how a specific piece of content performs, looking at page-level metrics is essential.
New visitors to a content page: How many new people are reading your content.
Interactions on a content page: How are people interacting with your content.
Bounce rate: Are people actually taking the time to read your content or “bouncing” away.
Value and conversions: How many people are taking action based on your content.Social Media Metrics
Looking beyond how people interact with content on a website or page, social media metrics – and especially signals – can give you a good idea of how people are reacting to your piece of content.
Reach: How big a potential audience is there to read your content?
Engagement: Are they sharing likes, Tweets, posts, shares, and audience growth rate?Branding & Awareness Metrics
Often overlooked because of its difficulty tracking and placing a direct measurement for, the importance of the impact content has on branding should never be ignored.
From traditional brand metrics to new ways of looking at branding online, they give a good indication of content performance used for corporate, PR, or internal marketing purposes.
Share of Voice: How content is performing compared to the competition (site or page level).
Branded versus Non-Branded search traffic: People searching for brand versus content without brand.Revenue Metrics
All measurements should lead to one final/most crucial metric – revenue.
The best way to get this may come from using a combination of the above metrics (converged media metrics) and applying some form of attribution modeling in areas where it is hard to see a direct $ connected to your content piece.
SEO metrics: Rank versus targeted keywords, quick answer results, inbound links.
Lead quality: New subscribers, content and landing page conversion and value.
Sales: Page value, assisted conversions, attributed score (via attribution modeling).Ensuring Your Content is Made to Measure
Keywords and keyword choice are vital pieces that are essential when writing for SEO.
The better you are the more you can measure – within reason.
You should know which keywords you’re optimizing for before you start writing.
Always keep these keywords in mind because you’ll find natural opportunities to include them in your content.
The keywords you chose should be a realistic reflection of your ability to rank.
Similarly, you should look for keywords with a reasonably high level of search volume.
Unless you have a super niche business, a monthly search volume of less than 100 won’t do you much good.Keywords & Intent
When you’re using SEO to drive organic traffic to your business website, you need to make sure you’re driving the right kind of traffic.
Volume for volume’s sake doesn’t help to accomplish critical business objectives.
This means you will have your measurement ladder up against the wrong wall.
A simple tactic for being purposeful with keyword choice is to consider the intent behind the term.
Keyword intent can reveal where someone is in the buyer’s journey, and your editorial calendar should be filled up with pieces that help customers at every stage.Body Copy
Although including keywords in your article is essential, it shouldn’t be the focus of the article.
Focus on writing the article in a natural way.
When creating content, think about what will resonate with your audience, and not just how to incorporate a specific keyword.
Going overboard could result in a penalty for keyword stuffing, so it is essential to keep an eye on your keyword density.URL (or ‘Slug’)
Search engines look at the URL of your content to understand what the post is about.
Make sure to include one or two keywords in the URL.
Remove any unnecessary clutter (dates, categories, etc.) in the URL so Google can more quickly determine what your content is about and whether it matches the searcher’s query.Meta Data
So make sure your target keyword appears here (naturally).
Also, while you’re at it, make sure your keyword is included in your title tag (if, for some reason, your headline and title tag don’t match).Readability
Several factors can influence how a page is ranked.
One crucial factor is readability.
Besides affecting your rankings, spelling and grammar mistakes can also hurt your credibility.
Which can undoubtedly have implications for your company’s bottom line.Visual Appeal & Optimization
Content that is only made up of text has never been the gold standard.
Images help break up complicated concepts and make content more engaging.
While you should use one image at a minimum, a great piece of content makes use of multiple images, screenshots, and examples within the body of the content as well.
Images can be optimized using keywords in the file name, alt text, title, and when appropriate, captions.
Part of image optimization is reducing image file size.
This has a lot to do with page load time, an important factor of technical SEO.
Video content can also help you to claim a highly coveted featured snippet for your given term and can help you to rank in different types of Search.
An easy way to boost the SEO value of a piece of content is to strategically share a video that complements the topic at hand.Shareability
Although there is no proven Google-backed link of social media’s connection to SEO, achieving some level of virality with your target audience can indirectly help with SEO through:
Building links: When people share or discover your content on these mediums.
Search visibility: Some posts from social media sites also come up in search engine results.
Increased traffic or conversions: Because more people are sharing content.Conclusion
A great piece of content takes time to create, time to rank, and time to accomplish specific business goals.
As such, it’s unwise to try and pump out content at a high frequency without a purpose behind it, or the time and effort required to give it the necessary SEO value it needs to find success.
SEO is a great way to measure content performance, and the value of content can span across the whole of your organization.
There is a subtly to measuring the SEO value of content.
Focusing on rankings too heavily can mean marketers miss the additional value of content marketing.
Rankings are only the beginning of your content measurement journey toward recognizing and attributing value.
What you measure in-between will make the difference.
The coordinate of a value in an R matrix is the row and column intersection that is the row and column index for that particular value. This can be found by using which function.
For example, if we have a matrix called M that contains value starting from 1 to 20 then we can find the coordinate of value 5 by using the command given below −which(M==5,arr.ind=TRUE) Example
Following snippet creates a matrix −M1<-matrix(rpois(80,10),ncol=4) M1
The following matrix is created −[,1][,2][,3][,4] [1,] 6 16 10 11 [2,] 10 4 15 10 [3,] 5 16 14 8 [4,] 8 11 14 13 [5,] 15 13 10 8 [6,] 10 11 6 13 [7,] 2 11 13 11 [8,] 6 16 15 10 [9,] 3 7 14 7 [10,] 8 4 10 11 [11,] 9 6 15 10 [12,] 14 12 11 10 [13,] 13 8 10 6 [14,] 7 13 11 4 [15,] 8 7 11 12 [16,] 12 13 9 12 [17,] 10 8 6 9 [18,] 3 11 8 9 [19,] 9 6 11 12 [20,] 10 18 12 9
To find the coordinates of value 11 in M1, add the following code to the above snippet −M1<-matrix(rpois(80,10),ncol=4) which(M1==11,arr.ind=TRUE) Output
If you execute all the above given snippets as a single program, it generates the following output −row col [1,] 4 2 [2,] 6 2 [3,] 7 2 [4,] 18 2 [5,] 12 3 [6,] 14 3 [7,] 15 3 [8,] 19 3 [9,] 1 4 [10,] 7 4 [11,] 10 4 Example 2
Following snippet creates a matrix −M2<-matrix(rpois(80,2),ncol=4) M2
