Are you thinking about using the Mathlib of R within GRASS C-code, or of 
calling R commands from within GRASS modules or scripts ?

How easy is it to call fonctions from R libraries in non-R code ?

Well you can run an R shell within GRASS, so what exactly do you mean by 
including one ?

I agree and as we are working on a C-version of d.vect.thematic, and 
Roger referred me to R for potential relevant code, actually including R
in the dependencies might makes things easier. At this stage I just 
don't know enough of R internals to know what the best approach would be.
