If you are using XP then create a shortcut to Rgui.bat, which
can be found in:
http://cran.r-project.org/contrib/extra/batchfiles/
0.2-7 is the most recent. When you install R it saves in the registry
the R version and Rgui.bat looks that up and runs that version thereby
giving you the last version you installed.
Rcmd.bat, also in batchfiles, does the same for running R from the
command line.
You can use Rversion.bat (or the gui version of that: Rversion.hta),
both from batchfiles as well, to change which version you want
it to use in the case that you have multiple versions of R on your
system.
There are also a number of other tools in the batchfiles collection
that can be of use in administering R on XP. The README in
batchfiles has more info.
