Thanks for your answer which was very helpfull. I have another question:

I have read in this document
(http://cran.r-project.org/doc/manuals/R-intro.pdf) that most of the
programs written in R are ephemeral and that new releases are not
always compatible with previous releases. What I would like to know is
if R functions are already validated and if not, what should we do to
validate a R function ?
