I don't have solution, but there is a remark on connection issues at http://code.google.com/p/ryacas/
An alternative could be to look at the rSymPy or rmathpiper packages which may do what you want.

Subject: [R] Ryacas loads but yacas has an error
Hello yet again, R People:
I was working with Ryacas and yacas last night and all was well.
Now this morning, I keep getting the following:
> a <- Sym("a")
Error in summary.connection(x) : invalid connection
When I go to yacas from the command line, it works fine.
Any suggestions, please?
I'm thinking that a port might be open, but here I have:

I'm working with R-3.0.1 on Windows 7.
