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?
