Subject: [R] symbolic math

Does anyone knows if it exists a "symbolic math" package in 
R, that allows to compute derivatives, integrals, etc.? 

Have a look at:
?D

Does exist a freeware version of Maple?

Not really a free version of Maple, but I use Maxima. You can find it
at:
http://maxima.sourceforge.net/

There you can do things like (just a simple, stupid example):
(%i1) diff(3*x^2,x);
(%o1) 				      6 x
(%i2) integrate(6*x, x);
	   						2
(%o2) 				     3 x
(%i3) 


(the spacing is a bit unfortunate in my email now)

Best, Roland
