I can't believe nobody here has mentioned PDL, the Perl Data Language: http://pdl.perl.org

Admittedly, i think R and PDL do different things... (I have never played with R).

Looks like PDL == NumPy (http://news.ycombinator.com/item?id=363159)

There are CPAN modules to directly use R from Perl (for eg... R::* & Statistics::R).

I have a stats friend who's been singing the praises of R & PDL for donkey years.
