Interesting remarks about R back in 1999
Hi, yes it's true Mathematica is too expensive (I think one of the most expensive out there), but yacas has a loooong way to go before becoming mathematica. I agree mathematica is not really for data analysis but I think it's to help researchers and inventors invent new ideas, understand concepts etc... However for that there is a "cheaper" alternative made out of three components: a pen, a paper and a human brain. The Rlink was available for free at some point; now it's not even there anymore!

...(snipped) Today, if I wanted symbolic mathematics, I might try Yacas
(http://yacas.sourceforge.net/homepage.html -- and the Ryacas package).
Mathematica is probably superior to Yacas, but I'd have to be convinced
that the difference was sufficient to justify the extra
expense...(snipped)
