This can happen. The default location of $RHOME has been changed at
some point (was /usr/local/share/R, now /usr/local/lib/R), or you may
have explicitly set it otherwise. If the location of $RHOME and the
startup script is unchanged, then I wouldn't expect problems, but it
should do no harm to delete them first in either case - but note that
this might kill add-on packages as well.

Where you put them... ;)


[pd at butterfly R]$ which R                     
[pd at butterfly R]$ more `!!`
more `which R`
# Shell wrapper for R executable.

export RHOME

If the startup script is gone, consider something like

find /usr -name R -prune
