[R] New package Ryacas

[Simon Blomberg]

Hi Gabor,

I'm running Quantian (Debian) inside a VMware virtual machine, on a 
Windows XP host.

I installed the latest version of yacas from the source tarball. I 
remembered to ./configure --enable-server to allow server connections. 
make and make install worked ok, after some fiddling. I checked that the 
yacas server option worked, by doing yacas --server 3333, and then 
telnet'ing to 127.0.0.1 3333 to check. It worked fine. I installed 
Ryacas. I then tried it out and got the following error:

 > library(Ryacas)
Loading required package: XML
 > yacas('Integrate(x)x;')
[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
 > Accepting requests from port 9734

I tried again (stubborn, I guess):                                       

 > yacas('Integrate(x)x;')
 [1] "Starting Yacas!"
 Accepting requests from port 9734
 YacasServer Could not bind to the socket
 : Address already in use
 /usr/local/lib/R/site-library/Ryacas/yacdir/R.ys(1) : File not found
 CommandLine(1) : Expecting ) closing bracket for sub-expression, but 
got x instead

Any ideas where I may be going wrong? I don't know anything about 
sockets. I've cross-posted to r-sig-debian. They may be interested.

Cheers,

Simon.
