R screencast tutorial

Dan Goldstein has a nice R video (screencast) tutorial on Decision Science News. The topics covered in this first tutorial are the very basics. I think it’s a great idea, and I think it’s very nicely done to start explicitly step-by-step with how to download and install it in Windows, how to run it, and how to execute commands that you have collected in a “script” file (command file). Doing a screencast is a good choice, too, because it makes all the steps clearly visible, especially the GUI interaction, where details important to the newbie user often get left out when an expert user types up what he or she is doing. (For example, users might not be familiar with choosing a mirror, or might not know that “r-base” is what they want to download).
