There are tools that help you improve your R packages, some of them are not famous enough yet in my opinion, so I was happy to help spread the word! I published my slides o...

How I became a crolute i.e. an user of the crul package

29.06.2017

A few months ago rOpenSci’s Scott Chamberlain asked me for feedback about a new package of his called crul, an http client like httr, so basically something you use for e.g. writing a package interfacing an API. He told me that a great thing about crul was that it supports asynchronous requests. I felt utterly uncool because I had no idea what ...

This week, a very promising new R blog was launched, namely the blog of Eric Persson a.k.a as expersso on Twitter.
