R(statistics): R introduction
From Karl Broman, my former stats prof over in Hopkins Public
Health.
Some of the pdf documents are good. The manuals are OK, but I
don't like manuals as a general rule. R main page (official)
We already have R installed on all of our workstations, both Linux and
windows, but if you want to put it on your own machine, you can
download it from this link. List
of commands - UCLA (don't try to learn R this way, but it is useful
if you already know and want a command for a particular function)
