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

Does exist a freeware version of Maple? Cheers, Marco I've just learned yesterday the use of expressions objects to compute derivatives. There might be functions for doing integrals as well. 1) define an expression using whatever symbol you like example: exp1 - expression(cos(x)+sin(y)) 2) Use function D() to perform symbolic derivatives: example: D(exp1,x) -sin(x) D(exp1,y) cos(x) You can find this stuff in R for Beginners, by Emmanuel Paradis (http://www.r-project.org/) Cheers, J -- Dr James Foadi PhD York Structural Biology Laboratory (YSBL) Department of Chemistry University of York Heslington York YO10 5YW UK __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

Re: [R] Symbolic math?
Hi, Have you tried Yacas? Yacas is a general purpose easy to use Computer Algebra System . It is built on top of its own programming language designed for this purpose, in which new algorithms can easily be implemented. In addition, it comes with extensive documentation on the functionality implemented and methods used to implement them. Is is open source. http://www.xs4all.nl/~apinkus/yacas.html Len Arne Henningsen [EMAIL PROTECTED] wrote: Hi, I sometimes use MuPAD (www.mupad.com).
