Sure. You can always use Perl to 'print' commands into a pipe to R. Or even
write them to a file, and then have Perl's backtick or system command
execute the file via R's batch mode.

There is a much higher-end interface available at www.omegahat.org, but it
sounds like you want something simple.

Google is your friend -- the 'call R from perl' query finds a total of
353,000 documents, including the aforementioned omegahat.org code as well as
prior discussions on this list.
