Sometimes my sarcasm is under-interpreted, but in this case no sarcasm
was intended. I told you in an earlier post that R does not do
symbolic algebra. Your counter-example points to a program that does.
Bottom line: R is not Mathematica. Complaining about that fact is not
going to get you anywhere. There is a package which provides an
interface to the open-source Yacas system if you want to pursue an R-
centric approach.
