Hello Anonymous Monk,

To be honest I have never used R either but I also found (The R/Splus--Perl Interface).

From the documentation:

This package provides a bidirectional interface for calling R from Per
+l and Perl from R. This embeds one interpreter (e.g. R) within the pr
+ocess of the other interpreter (e.g. Perl). One can call routines and
+ functions in the other language as if they were part of the local en
+vironment. This avoids having to program in a different language whil
+e making the functionality in the other system transparently availabl
+e with no additional coding. Values computed in one call are availabl
+e to future calls. This makes Perl more interactive, also allows the 
+R/Splus programmer to use convenient and familiar syntax to mix compu
+tations in the two different sytems, and provide statistical function
+ality to Perl applications..

Maybe a bit of more documentation could help on how to use it (How to use RSPerl).

Hope this helps.
