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")
> 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:
> showConnections()
     description class mode text isopen can read can write
>

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

Thanks,
Erin
