[STATSGRASS] Re: Connecting to databases on Windows using R

I followed the directions from bioconductor FAQ/Windows section and using
getBioC was able to get Rbdi again, but RdbiPgSQL isn't appearing (or
Rdbi.PgSQL).  It will open the site and load everything else that I want/need,
but RdbiPgSQL isn't to be found.  

R returns the message:
Unable to locate the requested package(s) in any known repository

getBioC("database") should be loading Rdbi and RdbiPgSQL, but when I try to call
them up through R, Rdbi will work, but RdbiPgSQL isn't in the library.  

Using install.packages2("RdbiPgSQL") gets the same response: it can't find the
package.

I also tried to install RMySQL, which is supposed to be supported for R on
Windows, but isn't in the CRAN repository.
