If you want to lighten up your Friday and learn something about R in the process, check out this list of R Resources at Cerebral Mastication, J. DeLong's blog. The descriptions alone are a treat, like this one for A (not so) Short Introduction to S4:
I think that trying to write a short introduction to S4 object programming in R is like trying to write a brief summary of the Arab/ Israeli conflict. You end up with 68 pages and it feels like you didn’t give it justice and left all the exciting bits out. If you don’t know what S4 objects are you will find the answer on page 2 of this manuscript. Then you can have drinks with your computer scientist friends and sound like you are not a total idiot. Although if you are having drinks with computer scientists, you may not be an idiot, but you probably are a nerd. I mean that in the best way possible, nerdboy.
David, you fantastic nerdboy, you. Thanks for the giving me a little mastication right here on your blog. My content is a little stale on my blog as I am in the middle of moving my whole family to Chicago from Virginia (what the hell is wrong with me?) But soon I will get the mental mastications back up and going. Thanks again. Keep up the good blogging. You're my second favorite blog... right after that one with free pr0n.
