There are several sources for information on R.  Most information on S+ for 
instance will be pertinent.  Two published sources respecting R are An 
Introduction to R by Venables, Smith and the R Development Team.  Another is 
Introductory Statistics with R by Dalgaard.  There is also some extensive 
discussion in Open Source GIS: A GRASS GIS Approach by Marcus Neteler and 
Helena Mitasova.
