Re: Feature Request: Vector math functions

FWIW, I have heard about R as well and think that having access to the power of R library functions in PHP would be quite cool. My vote would be to look at R first as a possible math library for PHP and if this doesn't pan out then we could move on to something else. If R's GNU license automatically rules this out, let me know and I can help look for some other alternatives.
