[R] Problems with CRAN package Ryacas

[Gabor Grothendieck]

We have had Linux users that successfully used Ryacas but if you can't
get yacas to build on your particular system then you could try
running the Windows version under wine.  A Windows binary of yacas is
available so you won't have to build yacas.  I don't know if anyone
has tried that yet but its worth a try.

Another possibility is to try rsympy or rmathpiper (see introductory
paragraphs on Ryacas home page for links).
