I'm trying to install the RWeka package for R 2.14.1 running on Ubuntu Linux 12.04. I type:


choose a mirror and it downloads.

Then I get these messages:

configure: error: Java Development Kit (JDK) is missing or not registered in R
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.

ERROR: configuration failed for package ‘rJava’
* removing ‘/home/~/R/x86_64-pc-linux-gnu-library/2.14/rJava’
ERROR: dependency ‘rJava’ is not available for package ‘RWekajars’
* removing ‘/home/~/R/x86_64-pc-linux-gnu-library/2.14/RWekajars’
ERROR: dependencies ‘RWekajars’, ‘rJava’ are not available for package ‘RWeka’
* removing ‘/home/~/R/x86_64-pc-linux-gnu-library/2.14/RWeka’

The downloaded packages are in
Warning messages:
1: In install.packages("RWeka") :
  installation of package ‘rJava’ had non-zero exit status
2: In install.packages("RWeka") :
  installation of package ‘RWekajars’ had non-zero exit status
3: In install.packages("RWeka") :
  installation of package ‘RWeka’ had non-zero exit status

So I quit and type:

sudo apt-get install icedtea-7-plugin

Let that run, then:

Updating Java configuration in /etc/R

Then I go back and start R and type install.packages("RWeka")

and get the same error message as before.

Any suggestions?

This question came from our site for professional and enthusiast programmers.

@ShivanRaptor: This looks like a problem that any user of R on Ubuntu could run in to, it's not really specific to sysadmins, I don't think? – Marius Jul 23 '12 at 6:00

It looks like you might have the JRE (Java Runtime Environment) installed, but not the JDK (Java Development Kit).


sudo apt-get install openjdk-6-jdk

Then try to install the package again.
