[R] unable to load library rJava on my Ubuntu 9.04

[Lazarus Mramba]

Dear all,

I have been running R-2.9.1 on Windows without any problem. I decided to run it on my Ubuntu 9.04 where i have R-2.8.1 and I have a problem loading the package JGR because it cannot load the dependancy rJava. This is a cool editor I would wish to use while on Ubuntu.

Here is a copy of the errors i get:

library(JGR)
Loading required package: rJava
Error in dyn.load(file, DLLpath = DLLpath, ...) : 
  unable to load shared library '/usr/local/lib/R/site-library/rJava/libs/rJava.so':
  libjvm.so: cannot open shared object file: No such file or directory
Error : .onLoad failed in 'loadNamespace' for 'rJava'
Error: package 'rJava' could not be loaded


This means I managed to download the rJava package   '/usr/local/lib/R/site-library/rJava/libs/rJava.so':
  libjvm.so       ... but It cannot be loaded. What do I do?


Problem 2: I have tried in vain to get the newer R version of 2.9.1.   I keep on getting the 2.8.1.  I have read the instructions from the R site but I seem not to be there. What do I do?

Kind regards,
