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?
