Ok, more seriously it can depend on what you want to do with Perl.
You can use the system or shell command to run any external program including
perl.
You can open up a pipe connection to send info to or get info from external
programs including perl.
There is the Rsperl interface (http://www.omegahat.org/RSPerl/)
The book S Poetry (http://www.burns-stat.com/pages/spoetry.html) has a 'perl'
function that will run perl commands on a character vector (takes care of the
exporting/importing for you).
If you just want Perl for the regular expressions, there are R functions such
as regexpr that can use Perl regular expressions directly inside of R (link to
pcre).
There may be other options, which is best depends on what you want perl to do
for you.
Hope this helps,
