The R Days took place at the end of June 2017 in Anglet, France. The slides of the various presentations have been made public on github

I just attended the first day (the program is available on the site. Here are the highlights:

• 9h-10h : Invited speaker; Marie-Pierre Etienne. Ecology Analysis using R
