When installing rJava using the install.packages(\"rJava\") command I get the following error:

Answer 1

Turns out my problem was an issue with my JAVA_HOME environment variable. Yes, shocking I know. My initial setting for PATH and JAVA_HOME looked like this:

export JAVA_HOME=/usr/lib/jvm/java-6-sun
export PATH=$PATH:$JAVA_HOME/bin

And I added /jre so it now looks like this:

export JAVA_HOME=/usr/lib/jvm/java-6-sun/jre
export PATH=$PATH:$JAVA_HOME/bin

Everything in Java seemed to work fine without the /jre but rJava would not. Odd.
