[R] Problem in installing rJava from source

[Joshua Wiley]

Hi,

rJava depends on having appropriate version of Java installed.  You
can download the JDK from oracle for free at their website.  It should
automatically set the appropriate environment variables, but if you
are having difficulty with that still, you may need to set JAVA_HOME
to the directory where you installed Java.

Cheers,

Josh

P.S. Duncan Murdoch's Rtools gives you what you need to build R and
many packages but not all third party software a particular package
may depend on.
