Maps with R: slides

The other day, someone asked me if it was easy to do maps with R. My first thought was: “of course, it is”. I offered to prepare a few slides. I guess it was not that simple after all because one actually needs quite a lot of basic knowledge to be able to create its own map.

Coordinates of “hot-spots”

Last week I uploaded a note about the paper @freakonometrics and I have submitted again after we added quite a few revisions. We have already made available most of the R code to reproduce our applications (on this GitHub repository). However, we did not share our method to obtain the coordinates of the “hot-spots” areas

Pense-bête R #1 (deux courbes sur un graph)

Il m’arrive souvent de fouiller dans mes fichiers pour tenter de retrouver un code R pour produire un graphique, ou manipuler des formats (comme par exemple des dates). Un moyen rapide de retrouver les informations serait de publier mes code sur ce blog. Il est même possible que certaines personnes puissent y trouver un léger intérêt. C’est pourquoi je souhaite commencer une série d’articles intitulés “Pense-bête R”, qui sera alimentée à chaque fois que je rencontrerai un cas de figure sous R que je risque de rencontrer à nouveau.

Tweet goes viral

To begin this new year, I had the pleasure to have some fun with R, Gephi and Twitter.
