It was recently brought to my attention by Hannah Frick that there are now sooo many R-Ladies chapters around the world! R-Ladies is a world-wide organization to promote gender diversity in the R community, and I’m very grateful to be part of this community through which I met so many awesome ladies! Since we’re all connected, it has now happened quite a few times that R-Ladies gave talks at chapters outside of their hometowns. An R-Lady from Taiwan giving a talk in Madrid while on a trip in Europe and another one doing the same in Lisbon, an R-Lady from San Francisco presenting at the London and Barcelona chapters thanks to a conference on the continent, an R-Lady from Uruguay sharing her experience for the New York City and San Francisco chapters… It’s like rockstars tours!
Therefore we R-Ladies often joke about doing an exhaustive global tour. Hannah made me think about this tour again… If someone were to really visit all of the chapters, what would be the shortest itinerary? And could we do a cool gif with the results? These are the problems we solve here.

I’ve recently been binge-reading The Guardian Experience columns. I’m a big fan of The Guardian life and style section regulars: the blind dates to which I dedicated a blog post, Oliver Burkeman’s This column will change your life, etc. Experience is another regular that I enjoy a lot. In each of the column, someone tells something remarkable that happened to them. It can really be anything.
I was thinking of maybe scraping the titles and get a sense of most common topics. The final push was my husband’s telling me about this article of
Gabriella Paiella’s about the best Guardian Experience columns. She wrote “the “Experience” column does often touch on heavier topics”. Can one know what is the most prevalent “weight” of Experience columns scraping all their titles?

I am a runner but also a Body Pump enthusiast. Body Pump is a group fitness class of the Les Mills company, in which you train different muscle groups using a weighted bar – whose total weight you modulate with plates in order to adapt it to your fitness level and to the muscle group. Like R, Body Pump was created in New Zealand, what a wonderful country! Every three months, a new class is released, with new songs and choreographies. What doesn’t change is the muscle group trained in each of the 10 songs of each class.
I’ve thought of analysing Body Pump data for a long time now but could never find what I was looking for, which was a dataset of number of “reps” by song, e.g. how many squats do you do in each squats song. Then I realized I could also play with other data, like a quite comprehensive list of songs used in releases. I decided to cross this information with information about style of the corresponding artist in Spotify. Here is what I came up with!

Emojis were again quite en vogue this week on Twitter with Romain François doing some awesome stuff for the
emo package, in particular this teeny tiny animated clock. It reminded me of my own emoji animated clock that I had done a while ago for representing time-use data. Time for me to present its genesis!

Today I made a confession on Twitter: I told the world I had spent my whole career not naming chunks in RMarkdown documents. Even if I had said one should name them when teaching RMarkdown. But it was also a tweet for showing off since I was working on the first manuscript with named chunks and loving it. I got some interesting reactions to my tweet, including one that made me feel better about myself (sorry Thomas), and other ones that made me feel like phrasing why one should name RMarkdown chunks.
Hadley Wickham asked whether chunks were pets or livestock, as in his analogy for models. Livestock chunks are identified by numbers, not names, in the case of chunks defined by position. I now think we have good reason to consider them as pets and here’s why…
