Re: [R] Ryacas not working properly
Ryacas starts up yacas with an initialization file R.ys which puts
the server in a mode which outputs XML (which is what Ryacas reads).
It does that by specifying --init /whatever/R.ys on the yacas command line
when it is run.
You can run yacas without that init file or you can just enter into yacas
this to turn off XML output:
PrettyPrinter()
See the demo
demo("Ryacas-PrettyPrinter")
So if you are running yacas independently of R then
If you wish to run yacas outside of R just issue the command:
yacas
or maybe
yacas --init /dev/null
(untested)

There a side effect that I would like to remove: yacas compiled with

Re: [R] Ryacas not working properly
Gabor, >From what I can tell, telnet service is not actually required to run yacas. This is what confused me for some time and what raised the spectre of the concerns that had I for yacas to be dependent on telnet, as opposed to say ssh. On FC6 (and I suspect many other distros), telnet (plus or minus kerberos support) is not enabled by default, given the known security issues. One can, from the: System -> Administration -> Server Settings -> Services menu, select the "On Demand Services" tab and enable telnet there. This way, telnet is not running by default, but only when actually needed. After trying various permutations of settings, suspecting SELinux and/or firewall issues, I came to the conclusion that enabling this is not required. By default, the telnet server listens to port 23, which was another red flag that I had, noting the error messages for port 9734. I noted no problems from iptables (the Linux firewall rules), given that I do not have port 23 open for telnet service. When yacas is running, I see no indication that processes related to telnet are running, which should be the case, given that I have explicitly disabled telnet as root and SELinux enforces those settings based upon mandatory policies. Without digging deeper into the yacas engine, it may very well be that without the --server-enabled option, it does require a telnet server to be running as the means to pass the expressions for evaluation. However, with that option enabled, yacas has its own server and uses port 9734. I also noted no references to 'telnet' in the config.log, created during the build process. However, I could not get yacas working without the server related option, even with telnet enabled, SELinux in Permissive mode and the firewall disabled on my system. This interaction was a great source of confusion, so it would be worthwhile to query the yacas folks to get some clarification relative to the presumptive dependency on telnet, which may end up being OS specific.

Re: [R] Ryacas not working properly
I had an offline discussion with the Debian user and he indicated that
the yacas invocation string was his problem and not telnet at all so I will
remove that HowTo as it is indeed misleading.

Re: [R] Ryacas not working properly
I don't have a UNIX box but my reading of it is that it is
telling one how to enable telnet on the machine -- not
how to install a server -- and that once telnet is enabled
then the Ryacas package can make use of sockets
whereas without that such use of sockets is disabled.
Is that not right?

Apparently, the link
"HowTo - Enable Telnet on Linux"
at Ryacas site is misleading, as it suggests the installation of
telnet-server and that is not necessary. See the discussion at

Re: [R] Ryacas not working properly
Thanks, Marc. I have placed a link to your post on the Ryacas home page.
Also, Ryacas 0.2-3 is now on Omegahat (as well as google groups).

Re: [R] Ryacas not working properly
OK, after digging around for a couple of hours on this, thinking that
this might be a firewall/SELinux/"On Demand Services" problem, I have, I
think, nailed it down to two key things on FC6:
1. It requires the use of the '--enable-server' configure option for
yacas itself.
2. There is a directory permissions problem in the Ryacas package,
restricting a regular user's access to the files located in the 'yacdir'
subdirectory.
Note that in the instructions below, I also install the GSL, which
presumably is not required, but I did it anyway after noting some
warnings during the yacas build process.
One other thing, which is that when downloading the Ryacas package from
the Google site using Firefox, the file is downloaded as:
Ryacas_0.2 3.tar.gz
Note the missing '-' between the 2 and 3. Be sure to check for this
when saving the tarball to disk.
So here goes:
1. Install the GSL (including the devel RPM) as root:
yum install gsl*
2. Install yacas from the source tarball using:
./ configure --enable-server
make
then as root:
make install
4. Install the Ryacas package as root:
R CMD INSTALL Ryacas_0.2-3.tar.gz
Be sure that you also have the 'XML' package from CRAN installed, which
is a dependency for Ryacas.
3. Change the permissions for /usr/local/lib/R/library/Ryacas/yacdir:
Note that the default permission for this directory after installation
is:
drwxr--r-- 2 root root 4096 Nov 19 15:17 yacdir
Thus:
su
chmod +x /usr/local/lib/R/library/Ryacas/yacdir
Now:
drwxr-xr-x 2 root root 4096 Nov 19 15:17 yacdir
Now in R as a regular user:
> library(Ryacas)
Loading required package: XML
> yacas("5/8 * 3/4")
[1] "Starting Yacas!"
Accepting requests from port 9734
expression(15/32)
> yacas("3/7 * 5/9")
expression(5/21)

Re: [R] Ryacas not working properly
Sorry but there is not much else I can tell you. I don't have a UNIX system
myself though I do know that others have used Ryacas on UNIX since the notes
on the home page are based, in part, on their feedback of successfully using
it on UNIX.
I don't know if the responder is correct since one other person who had a
similar problem on UNIX with Ryacas found that it was his telnet configuration
that was the problem.
Make sure you have tried all the possibilities on the home page.
You should at the very least be able to run Ryacas using the system method
since that does not require telnet in the first place.
Also check which version of Ryacas you are using.

Thanks, Peter. I put there port 9734, but no progress. Meanwhile, I

you don't want to touch the /etc/xinetd.d/telnet file (if you had one).
that file relates to control of the telnet daemon - which is what the
user in that google groups message was trying to get going.
you're not interested in the telnet daemon, rather in the ryacas one,
and that's what you should focus on trying to get working. your issue
with not being able to connect to port 9734 is because you haven't
managed to get the ryacas daemon started up correctly. when you do, and
it shows up in a netstat, then all should be well.
in short, your problem is with setting up ryacas, not "enabling telnet".
in your context, your telnet client, which works just fine, has nothing
to do with your telnet daemon (which appears to not be enabled, which
is just fine).»

In particular, check whether you're firewalling yourself out.
System/Administration/Security Level and Firewall -- I suspect that
you have to add the ryacas port there. ("Suspect" meaning that I'm not
sure that you really need this even for unprivileged ports on
localhost, but it could be worth the try.)

Re: [R] Ryacas not working properly
You might try posting your problem on the comp.os.linux.networking
group since it appears to be a configuration problem with telnet
on your machine.
If all else fails, you can try using the "system" method of connecting to
Ryacas discussed on the Ryacas home page.That is not ideal since it
will not give you any memory from one Ryacas call to the
next but it will allow you to do command at a time Ryacas processing
even without telnet. Note that you mus be using Ryacas 0.2-3 (which is
located on google groups -- see links section on home page) and not
0.2-2 for that to work.
