You could call R in BATCH mode from the perl script using
one of the system interface operators, e.g., "system", or use the 
'Shell' module.

I have also bumped (but didn't try yet) into R-Perl interface 
called RSPerl which might be much more than you what you need.
I think it is under the "Omega" link in the R website. If not
google for RSPerl.

'R --help' will give you pointers to running R in BATCH mode.
