Genetic algorithms / evolutionary computing _are_ already available via CRAN,
see eg rgenoud and DEoptim. Wrapping existing ones is also fairly easy; I am
sometimes use PGAPack from R at work (using non-released code).
As for Jave, as I understand it, rjava is _the_ common interface.
I prefer C++ and use RCpp (now on r-forge.r-project.org) and there are
parallel discussions going on regarding Swig.

i) Use the dedicated front-ends to searching as eg RSiteSearch("foo") from
within R, or
ii) combine your search terms with terms like 'r-help' or 'r-devel'

There are several lists/usenet gateways like eg gmane. See the R FAQ/
Three out of two people have difficulties with fractions.
