Data Geeks!
Feb. 5th, 2013 04:04 pmO'Reilly is offering a free course on the basics of R. With pirates. I've done a few of the modules and I really like the setup for getting a good feel of the command line, data types, etc.
Download R (for free!) here:
http://cran.r-project.org
The tutorial is here:
http://tryr.codeschool.com
(You can try the tutorial without downloading the package)
Also I recommend SimpleR as a good free reference. For anyone who's ever looked at a data set and said, "If only I could plot it that way..."
ETA: I should also say, that for any spot where they use the arrow assignment '<-', you can also just use the equal sign '='
