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.
