Yep, I think Martin is right.  For Emacs to find "R-alpha", you need
to be able to run "R-alpha" from any directory; above you state it can
be run using "./R-alpha" in just the two directories, so it won't
work.  in your bash shell, add somethng like:

export PATH="$PATH:$HOME/bin/"

and restart a bash shell, and try emacs agagin.
