JGR on SUSE 10.1 AMD 64

Dear list;

I have R Version 2.3.1 (2006-06-01) installed on a AMD 64 machine with SUSE 
10.1. 

I have Sun Java version 1.5.0-sun installed. 

I have used "install.packages("JGR", dep=TRUE) to install rJava, iplots and 
JGR. I would like to do a presentation of linux and R for the department!

Compiling rJava do not give any error messages!

But when trying to load library("JGR") or just library("rJava") I get the 
following error message:

Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library  '/usr/lib64/R/library/rJava/libs/rJava.so':
libjvm.so: kan inte ?ppna delad objektfil: Filen eller katalogen finns inte
Error in library("rJava") : .First.lib failed for 'rJava'

I have the same configuration: adding various library paths for the 
missing libs before calling R made the installation succeed:

export
LD_LIBRARY_PATH=/usr/lib64/R/lib:
/usr/lib64/jvm/java-1.5.0-sun-1.5.0_07/jre/lib/amd64/server:
/usr/lib64/jvm/java-1.5.0-sun-1.5.0_07/jre/lib/amd64:
$LD_LIBRARY_PATH

This is something that is set up when R is configured, and stored in 
R_HOME/etc/ldpaths.  Has perchance your Java subsystem been updated since 
R was installed?  

In which case update R_HOME/etc/ldpaths as appropriate, 
or set R_JAVA_LD_LIBRARY_PATH (not LD_LIBRARY_PATH) to override the 
setting there.

True.

That's much better. Thank you.
