It looks like you to save the contents of r() as well.
Good catch. I still think the world would be a better place if my
original code worked. You would think that the -post- option could
ereturn whatever -marginsplot- needs and/or -marginsplot- could be
smart enough to know when it is working with posted results. If that
can't be done, maybe there could be some simple commands that saved
or stored the e and r results simultaneously.
