Dear All

I have just installed the package Ryacas, but getting the following:

> library(Ryacas)
Loading required package: XML
> yacas("1/2 * 3/4")
[1] "Starting Yacas!"
Error in socketConnection(host = "127.0.0.1", port = 9734, server = FALSE, :
    unable to open connection
In addition: Warning message:
127.0.0.1:9734 cannot be opened
> /usr/lib/R/library/Ryacas/yacdir/R.ys(1) : File not found
>

I am using Fedora Core 6 (Linux), R 2.4.0 and Yacas 1.0.62.

Any ideas?

Thanks in advance,

Paul
