You need to install Java. That seems not to be in the rJava
documentation: you get it from here:
http://www.oracle.com/technetwork/java/javase/downloads/jre7-downloads-1880261.html
and need the version for the version of R (32- or 64-bit, x86 or x64 in
Oracle parlance) you want to run.
Please do follow the R-help posting guide and not send HTML, and give
the 'at a minimum' information asked for (which includes that this is
Windows i386 or x64).

I tried various things with searhpath, but can't figure out if this a
windows 7 problem, an R problem, an R-studio problem, an R4 vs R3
problem, an rJava problem, a firewall problem, or some clever
combination of such problems. Any tips greatly appreciated even if all
they tell me is in which direction to look (e.g. give Windows a
different searchpath?)
