A key piece of information not in your original post was that you were
not "installing" R, but wanted to run it from whence it was built...and
then moved it and were attempting to run it from a new location.

You will need to change $R_HOME, which defines the primary home
directory for the currently running R session.  This is defined in the
main R startup script, which will be in the 'bin' sub-directory for your
R tree.

I have not validated this that will do it, but short of re-building R in
the new location, this should work I think. Many of the environmental
vars are hard coded during the build process and then modified during a
"make install" based upon build time configuration options. If you want
to install R in a non-default location, I would suggest considering
modifying the ./configure options and then building to suit your needs.

HTH,
