I want to have Sage use the executable of R that's already on my machine instead of the one that comes with it (it's newer, already has all my packages installed, etc). How do I configure Sage to run that version of R by default?
I don't know if it's possible to do this "by default". You could try the following, though (warning: this is untested):
set the environment variable R_HOME to point to the location of your R installation (right now, it is essentially set to $SAGE_ROOT/local/lib/R).
delete the file $SAGE_ROOT/local/bin/R and replace it with a symlink to your R executable. I don't know if $SAGE_ROOT/local/bin/Rscript needs similar treatment.
