Title: library(grid) call at the R script header

I've simply added a "library(grid)" call at the beginning of the R script generation since R 2.14.2 doesn't seem to load the "grid" package as default. I haven't tested it on previous R versions (you may edit the R version comment to be more precise if desired), but I'm almost certain that this library call shouldn't do any harm on them.
