I wouldn't try and use both rpy and rpy2 in the same script.
Also you don't seem to be using the os, time, string, sys, and
shutil modules anywhere.
The most important question is does that embedded R script
work in R?
Also check the newlines (which have probably been messed up
by pasting into the email). Perhaps a few semi-colons in your R
code would help here to make the end of each statement explicit?
