Well, it will unpack in a separate directory and you can build and
test the new version there, it is only when you enter "make install"
that you'll be overwriting files in system locations. The R-0.65.1
directory can be kept if you wish.

Normally, no harm comes from installing on top of a previous
installation, but if you want to be sure delete /usr/local/bin/R
and  /usr/local/bin/*Rd* (hoping that nothing else matches the
wildcards...) and "rm -rf /usr/local/lib/R" befor installing.

If something goes haywire, it should still be possible to go to
R-0.65.1, type "make install" and have the old version reinstalled.

All assuming that you used "make install" with the standard locations
the last time round.
