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
