How to Become an Efficient and Collaborative R Programmer

December 12, 2011

I may want to add a subtitle “Why R-Forge Must Die” (thinking of Barry Rowlingson’s talk earlier this year). I have been a GitHub user for two years, and I was mainly influenced by Hadley. Now I even feel a little bit addicted to GitHub (its slogan is “social coding”), because it is really convenient

The fun Package: Use R for Fun!

A couple of days ago we released a package named fun to CRAN, but I did not dare to send an announcement to [email protected] as usual. This package is a collection of some classical computer games (e.g. the Mine sweeper and Five in a row) as well as other funny stuff. Some examples: ## install.packages('fun')

Produce Authentic Math Formulas in R Graphics

I remember a few weeks ago, there was a challenge in the R-help list to make the prime symbol in R graphics. In LaTeX, we simply write $X'$ or $X^\prime$. R has a rough support for math expressions (see demo(plotmath)) and they are certainly unsatisfactory for LaTeX users. In fact we can write native LaTeX
