Thanks for saving me a shameless plug (notice that the double a comes last, though...).
For people just out to get their feet wet, there's also a collection of shorter and longer documents in the contributed section on CRAN, http://cran.r-project.org/other-docs.html . I particularly like Jason Owen's "The R Guide" as a kickstart document. As far as I can tell, you can just skip things that rely on math that you haven't heard of (such as matrix algebra) without getting lost. -pd > > Abhijit > > Anja und Th.
