Thanks Dirk.
I should have noted the debian sig. My question -- as Dirk recognized --
was where to let folk
know. Part of the issue is that Ubuntu users who are new to R may not
find this stuff. My
workaround may also be a pointer for those with other Linux distros.
There is now another issue that I don't find r-cran-java as an available
package when I
run the apt-cache search. (I do find r-cran-rgl; rgl popped up as a
dependency in the
install.packages, but I should have looked for the debian package.)
I'll post my r-cran-java query to the r-sig-debian.

| Ubuntu Hardy rgl install fix:
|
| The headers gl.h and glu.h are installed with the "dev" packages
| libgl1-mesa-dev and libglu1-mesa-dev. So the fix is to run (in at
| terminal as root)
|
| apt-get install libgl1-mesa-dev
| apt-get install libglu1-mesa-dev
Yes, which is why the r-cran-rgl package (available in Debian for over five
years now, and hence in Ubuntu for probably 4 1/2) has the following
Build-Depends (with my manual indentation here):
Build-Depends: debhelper (>= 5.0.0), r-base-dev (>= 2.8.1), cdbs, \
libgl1-mesa-dev | libgl-dev, libglu1-mesa-dev | libglu-dev, \
libpng12-dev, libx11-dev, libxt-dev, x11proto-core-dev
| then
| R
| .....
| install.packages("rgl")
|
| etc.
Let's not forget the 'sudo apt-get install r-cran-rgl' alternative.
| Ubuntu Hardy rJava install fix:
|
| Needed to get Sun JDK (not JRE)
|
| Then add new
| ln -s /usr/java/jdkxxxxx/bin/java java
| and
| ln -s /usr/java/jdkxxxxx/bin/javac javac
|
| where xxxxxx is the version information on the jdk directory name -- in
| my case 1.6.0_13 (see below)
|
| Then
|
| R CMD javareconf
|
| still fails to find the java compiler.
|
| Seems $JAVA_HOME may not be defined.
|
| Try
| export JAVA_HOME="/usr/java/jdk1.6.0_13/"
|
| Then (as root)
|
| R CMD javareconf
|
| seems to work.
| Then rJava installed OK. I was then able to install RWeka (my original
| objective) and it seems to run OK.
Likewise, the r-cran-rjava package has
Build-Depends: debhelper (>= 7.0.0), r-base-dev (>= 2.8.1), cdbs, \
openjdk-6-jdk, automake
and R is now configured for this Java version at the built.
Again, questions on the r-sig-debian list may have been of help.
Hope this helps, Dirk
