[R] replace a value in a vector

[Paul Lepp]

OK, so this is a really stupid question and should be incredibly simple to
do but I can't figure it out. So maybe someone would be so kind as to tell
me.
I have a vector of zeros and ones.  I want to replace all of the zeros with
"black" and all of the ones with "gray".  That's it.  Any help would be
appreciated.

Thanks,
Paul
