Summary of using R from within Perl
Many thanks to Duncan Lang and Patrick Connolly for their very helpful
suggestions.
I used ldd to look up R.so and was told that libR.so was not found.
After I changed LD_LIBRARY_PATH, it worked!

calling R from Perl

RSPerl on www.omegahat.org which should do what I need. However in
the description it says it has been tested with R 1.3.* the latest.

R/Splus--Perl Interface && ssh
Hi:
I'm using RSPerl_0.6-3 calling R from Perl under UNIX system. My perl programs with the RSPerl work well in my computer. If submitting these programs to a UNIX system by 'ssh' or to GNQS system by 'qsub', these programs do not work even though both systems can run R. Details are following. Any suggestion will be highly appreciated.
