Hi,
I'm just about to install the Precompiled Binary Distribution of R from
CRAN for SuSE Linux 8.2: R-base-1.7.1-1.i386.rpm
My system is SuSE Linux 8.2 Professional Edition on a Pentium 4:
# uname -a
Linux linux 2.4.20-4GB #1 Mon Mar 17 17:54:44 UTC 2003 i686 unknown
unknown GNU/Linux
1) Problem:
I've tried to install the above base rpm archive with the command:
# rpm -i R-base-1.7.1-1.i386.rpm
error: failed dependencies:
libg2c.so.0 is needed by R-base-1.7.1-1
There seems to be only one dependency missing (hope that's all). Since
I've installed the Professional Edition with all the compilers and
libraries, it's maybe only a naming problem.
What's behind this missing library?
Can this problem be fixed with a symbolic link pointing to a library
that I already have on my system?
Any experience with that?
Do you think I need or should compile and install R myself (not using
one of the binary distributions)?
2) Question:
I want to use R not only interactively (issue commands after the prompt
> ..), but also use some functionality of R from a Perl script.
Can I use methods of R from a Perl script: Is there an interface from
Perl (or at least from C/C++) to R (f.e. invoke R functions from Perl,
C, C++ or some other language)?
If so, can you please point me to the documentation on the Web or in
literature where this is decribed?
Do you have some demo Perl script (or C/C++ program) that uses this
technique, f.e. calling R methods like "mean" or "standard
deviation"?
Thanks's for your help!
Regards
Bernhard

Be warned that these Omegahat packages are sometimes not quite as stable as the regular CRAN family of packages so some patchups can be required. Or maybe it will all just work... -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.

But in this particular case, based on guesstimation from the name of the missing rpm, I bit you would need it anyway. Another way to find missing rpms is by typing in the name of the relevant file in the search section of http://rpmfind.net/linux/RPM/>2) Question: > >I want to use R not only interactively (issue commands after the prompt > > ..), but also use some functionality of R from a Perl script.It is better to ask one question per email. If this were the only one, I wouldn't answer. But I have noticed that Rweb uses Perl with R: http://www.math.montana.edu/Rweb/ There is also a CGIwithR package that I haven't tried, and I don't know what it does. -- Jonathan Baron, Professor of Psychology, University of Pennsylvania Home page: http://www.sas.upenn.edu/~baron R page: http://finzi.psych.upenn.edu/ deleting "Your details" "Your application" "Approved" "Thank you!"
Bernhard -
1) DO try building from source. For me it works painlessly
(Redhat 8.0 linux) and ./configure seems to be very good at
locating the resources it needs.
2) The very easiest, dumbest interface between Perl and R is
for Perl to write an ascii file of R commands - exactly what
one would type at the command line, including maybe
'object <- read.table("file.name")' to read in data from a
second file - then run this script as: R BATCH scriptfile outfile.
Wait for this to finish, then read outfile back into Perl.
I can't help with fancier methods, since I've never tried.
