rOpenSci post-doc hacker Jeroen Ooms has just released a cool new package,
av, that he wrote “will become the video counterpart of the magick package which [rOpenSci uses] for working with images.”.
av provides bindings to the FFmepg libraries for editing videos. It’s already become a renderer for
gganimate by Thomas Lin Pedersen, but
av allows more than making videos of graphics. In this post, I’ll show how to use
webshot to make a trailer/sneak preview of a slidedeck, i.e. a short video featuring the first few slides on music!
It’s October, time for spooky Twitter names! If you’re on this social
media platform, you might have noticed some of your friends switching
their names to something spooky and punny. Last year I was “Maelstrom
Salmon”, which I find scary but is arguably not that funny. Anyhow, what
if you want to switch your name but have no inspiration? In this post,
we shall explore R’s abilities to help us with that with the help of
webscraping, phonetic spelling and string distance algorithms, and the
magic of randomness!
What can a kaka, a kakapo, an European rabbit and a grey heron have in
common? Well, they might co-habit in the bookshelf of an R user, since
they’re all animals on the covers of popular R books: “R
Packages”, “R for Data
Science”, “Text mining with
R” and “Efficient R
Their publisher, O’Reilly, has now based its brand on covers featuring
beautiful gravures of animals.
Recently, while wondering what the name of R for Data Science bird was
again (I thought it was a kea!), I was thrilled to find the whole
O’Reilly menagerie, i.e. a list of
books and corresponding animals! The website also features a link to “A
short history of the O’Reilly
that was an amazing read. In it was noted that “The animals are in
trouble.”, with a few examples of endangered species. It inspired me to
actually try and assess the conservation status of O’Reilly animals
using responsible webscraping, taxonomic name resolving and IUCN Redlist
I was until recently subscribed to an email list, ALLSTAT, “A UK-based worldwide e-mail broadcast system for the statistical community, operated by ICSE for HEA Statistics.” created in 1998. That’s how I saw the ad for my previous job in Barcelona! Now, I dislike emails more and more so I unsubscribed, but I’d still check out the archives any time I need a job, since many messages are related to openings.
Last time I blogged, I offered my
obnoxious helpful advice for blog content and promotion. Today, let me again be the agony aunt you didn’t even write to! Imagine you have an R question, i.e. a question related to how you can do something with R, and your search engine efforts haven’t been too successful: where should you ask it to increase your chance of its getting answered? You could see this post as my future answer to stray suboptimal Twitter R questions, or as a more general version of Scott Chamberlain’s excellent talk about how to get help related to rOpenSci software in the 2017-03-07 rOpenSci comm call.
I think that the general journey to getting answers to your R questions is first trying your best to get answers locally in the documentation of R, then to use a search engine, and then to post a well-formulated question somewhere. My post is aimed at helping you find that somewhere. Note that it’s considered best practice to ask in one somewhere at once, and to then move on to another somewhere if you haven’t got any answer… or if someone kindly redirects you to a better venue!
