Update your Windows PATH – revisited

Yihui got me psyched a little about GitHub After my last post about running your R infrastructure from an USB drive, he commented on my function that would update the Windows PATH (which is at least important for R and Rtools). Now I found some time to polish it a little. Feel free to test … Continue reading...

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.

mean of an absolute Student’s t

Having (rather foolishly) involved myself into providing an answer for Cross Validated: “Can the standard deviation of non-negative data exceed the mean?“, I ended up having to derive the mean of the absolute value of a Student’s variate X.  (Well, not really, but then I did.)
