Upon request by the blog administrator, Tal Galili, I have joined R-bloggers, which aggregate blog entries about R into a central place. I feel I have much more to learn than to teach about R (as can be seen from earlier comments on my R programs in Introducing Monte Carlo Methods with R). As I was tagging some of my older posts with the newly created R category, I realised most tags were either about typos or books! Anyway, I figure joining a conglomerate of blogs cannot hurt!
