Re: R exercices

Are you familiar with R Inferno?  This is a programming-oriented 
tutorial for R by the statistician Patric Burns.  He has generously 
placed it as a pdf online for free 
(http://www.burns-stat.com/pages/Tutor/R_inferno.pdf); you could also 
purchase a copy.  Of course this will be more than just a few practice 
exercises (a lot more, and actually, I'm not sure there are any 
exercises but you can certainly follow along with the examples).  
Nonetheless, it may still be right up your alley.  There are other 
resources for learning the programming side of R, but only a few that 
are as good, and none other free, so far as I know.  If this is really 
different from what you're looking for, you may want to reply with more 
detail.

Hope that helps.  -Jeff
