[Rd] Computer algebra in R - would that be an idea??

[Simon Blomberg]

I would use such a symbolic math package for R. I have dreamt of an 
open-source solution with functionality similar to mathStatica. 
http://www.mathstatica.com/ Is yacas the best system to consider? What 
about  Maxima http://maxima.sourceforge.net/, which is also GPL, or maybe 
Axiom http://savannah.nongnu.org/projects/axiom, which has a modified BSD 
license?

Cheers,

Simon.
