Maëlle's R blog

I’ve now given my talk about “How to be a resilient R user” three times, at R-Ladies Strasbourg and R-Ladies Paris in person, and at R-Ladies San José via Google Hangouts. It was fun! I covered part of the content of that talk in a blog post about where to get R help. Today, it’s time for a post full of my personal opinions! I’ll cover the rest of the talk: why and how stay up to date with R news?

Here we go again, using a Twitter trend as blog fodder! Colin Fay launched an inspiring movement by sharing his R goals of 2019.

My #RStats goals for 2019:

1️⃣ Becoming entirely fluent with {data.table}

2️⃣ Getting at ease with {Rcpp}

What are yours?#rdatatable #rcpp

It’s been quite interesting reading the objectives of other tweeps: what they want to learn, make, how they want to get involved in the community, etc. As Mike Kearney, rtweet’s maintainer, underlined, it is excellent reading material!

… but also blogging material! Let me fetch and tokenize these tweets to summarize them!

Disclaimer: I later saw that Jason Baik got the same idea and was faster than I, find the analysis here.

As 2018 nears its end, it’s time for me to look back on my R/Twitter year with the same simple method as last year: let me identify and webshoot my 9 best tweets of 2018!

You might have heard of the Advent of Code, a 25-day challenge involving a programming puzzle a day, to be solved with the language of your choice. I’ve noted the popularity of this activity in my Twitter timeline but also in my GitHub timeline where I’ve seen the creation of a few advent-of-code or so repositories.

AoC is largely an exercise in figuring how to write your favourite language as if were C or C++ 😁, which can be fun ... in moderation

If I were to participate one year, I’d probably use R. Jenny Bryan’s tweet above inspired me to try and gauge the popularity of languages used in the Advent of Code. To do that, in this post, I shall use the search endpoint of GitHub V3 API to identify Advent of Code 2018 repos.

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 av and webshot to make a trailer/sneak preview of a slidedeck, i.e. a short video featuring the first few slides on music!
