(This article was first published on <strong><a href="http://masalmon.github.io/2017/02/05/actuallivingscientists/"> Maëlle</a></strong>, and kindly contributed to <a rel="nofollow" href="https://www.r-bloggers.com/">R-bloggers)</a> </div>
<p>These last days a trending Twitter hashtag was “#actuallivingscientist”, whose origin can be find in <a target="_blank" rel="nofollow" href="https://twitter.com/darthmom7/status/827268431799922688?ref_src=twsrc%5Etfw">this convo</a> and whose original goal was to allow scientists to present themselves to everyone, a sort of #scicomm action. A great initiative, because we need science and we need everyone to know how it’s done, by actual human beings.</p>
<p>I didn’t tweet with the hashtag, but I consider myself a scientist with more or less experience <a target="_blank" rel="nofollow" href="http://www.masalmon.eu/bio/">in different fields</a> – and <a target="_blank" rel="nofollow" href="http://www.masalmon.eu/2017/02/03/chemist/">my last post</a> was about the scientist I married. In my timeline thanks to <a target="_blank" rel="nofollow" href="https://twitter.com/RallidaeRule">Auriel Fournier</a> there were many tweets of ecologists studying animals. I’d like to say <em>cute</em> animals but some were carcasses… But still, it made me want to quantify which animals were the most present in the tweets. Any bet?</p>
<p><span></span></p>
<h1>Getting tweets</h1>
<p>I got tweets thanks to Mike Kearney’s <a target="_blank" rel="nofollow" href="https://github.com/mkearney/rtweet"><code>rtweet</code> package</a>. I’ve done something similar in the past for <a target="_blank" rel="nofollow" href="http://www.masalmon.eu/2016/10/02/first7jobs-repost/">#firstsevenjobs tweets</a>.</p>

<p>Doing this I obtained 9611 tweets. Now let’s look for animals in them!</p>
<h1>Looking for animals</h1>
<p>Note: if Monkeylearn had an “animal extractor” module, I’d have tested a different approach with <a target="_blank" rel="nofollow" href="https://github.com/ropensci/monkeylearn">my own package</a> but it would have been really close to my <a target="_blank" rel="nofollow" href="http://www.masalmon.eu/2016/10/02/first7jobs-repost/">#firstsevenjobs post</a> a.k.a. as boring for you!</p>
<p>I have to confess I had never used Julia Silge’s and David Robinson’s <a target="_blank" rel="nofollow" href="https://github.com/juliasilge/tidytext"><code>tidytext</code> package</a> before. I read Julia blog (you should do that too!) though so I knew about <a target="_blank" rel="nofollow" href="http://juliasilge.com/blog/Song-Lyrics-Across/">the post</a> where she looked for the names of states in songs using <code>tidytext</code>, in particular a function calling Lincoln Mullen’s <a target="_blank" rel="nofollow" href="https://github.com/ropensci/tokenizers"><code>tokenizers</code> package</a> to split each song into words and bigrams (combinations of two words). I wanted to reproduce the approach, for this I only needed a list of animals and remembered <a target="_blank" rel="nofollow" href="https://github.com/gaborcsardi/rcorpora">Gabor Csardi’s <code>rcorpora</code> package</a>, which contains all datasets from <a target="_blank" rel="nofollow" href="https://github.com/dariusk/corpora">these corpora</a>. Including a list of animals, y’all!</p>

</div>
<p>A few animals are bigrams, for instance “grizzly bear” so I’ll really use the exact same approach and code as Julia in her songs post. In case you think I often end up copy-pasting R code from other people in my blog posts, please know that I often end up copy-pasting R code from other people <em>in general</em> when I do something for the first time.</p>

<p>Now for the animals <code>data.frame</code> I need names of animals in singular and plural form because tweets might contain animals in both forms. I first decided to just paste an “s” to the names since it’d work most of the time but then I realized Bob Rudis has a package for pluralizing and singularizing any English word, <a target="_blank" rel="nofollow" href="https://github.com/hrbrmstr/pluralize"><code>pluralizer</code></a>.</p>

<p>Much more elegant than my “let’s paste s” approach and I learnt that the plural of buffalo is buffalo! Also “mouses” wouldn’t be as useful as “mice”.</p>
<p>Now I can join the two tables and like Julia in her post I’ll only keep one occurence of an animal per tweet.</p>

<p>“cat” and “dog” get good rankings but they also are pets and I’ve even seen a tweet saying <a target="_blank" rel="nofollow" href="https://twitter.com/pooter03/status/827650864240275459">“I’m not an #actuallivingscientist but I have cute cats”</a>. This is still relevant for the hashtag because on the internet cats are always relevant, but it means we should be careful when interpreting these rankings. Also note that Cat can be someone’s first name (like Salmon can be someone’s last name). In honour of the cover of the <a target="_blank" rel="nofollow" href="http://tidytextmining.com/"><code>tidytext</code> book</a>, let’s look at rabbit tweets.</p>
