[R] Installing JGR and rJava

[gerald.jean at dgag.ca]

Hello,

I am running:

R version 2.10.0 (2009-10-26)
Copyright (C) 2009 The R Foundation for Statistical Computing
ISBN 3-900051-07-0

on a 64-bit RedHat box.

To encourage collegues to use R, I am trying to install "JGR", which
depends on "rJava", on the above machine.  At first I received and error
saying Java was not available.  My IT support, I am not admin. on this
machine, installed Java (1.6.0_19) and JDK (1.6.0_19) and successfully ran:

R CMD javareconf

now, I am getting the following error:

-------------------------------------------------------------------------------------------
.

.
checking Java support in R... present:
interpreter : '/usr/java/../bin/java'
archiver    : '/usr/java/../bin/jar'
compiler    : '/usr/java/../bin/javac'
header prep.: ''
cpp flags   : ''
java libs   : '-L/usr/java/jdk1.6.0_19/jre/lib/amd64/server
-L/usr/java/jdk1.6.0_19/jre/lib/amd64 -L/usr/java/jdk1.6.0
_19/jre/../lib/amd64 -L -L/usr/java/packages/lib/amd64 -L/usr/lib64
-L/lib64 -L/lib -L/usr/lib -ljvm'
configure: error: One or more Java configuration variables are not set.
Make sure R is configured with full Java support (including JDK). Run
R CMD javareconf
as root to add Java support to R.

If you don't have root privileges, run
R CMD javareconf -e
to set all Java-related variables and then install rJava.
--------------------------------------------------------------------------------------------
as I said previously "R CMD javareconf" was ran.  As suggested by the error
message I also tried to run:

R CMD javareconf -e

although it ran without error it didn't help?  What are these
"configuration variables" and how do we set them?

Anyone has and idea on how to fix this?

Thanks for your support,
