I think that people are afraid to say "You can't do that in R"...
But I think the real answer is: you can't do that in R.

Although, it is helpful to understand Jeff's reply.  I hadn't fully
realized why this particular problem occurs before reading that.  It's odd
to me that // and / are both stored as /, but that makes sense given my
experience in R.

Also, the other replies are good advice, working with R's path functions or
sticking with forward slashes is the way to go (don't fight the
assimilation, the borg needs you).

Personally, I think some of these seemingly small problems actually
encumber R's mainstream adoption quite a bit, but then I'm not the one
writing R.  Plus, it's is still pretty dang awesome even with its minor
annoyances.
