? backslash was Re: [R] Editor alternative

[Yves Gauvreau]

Hi

I just want to point out an observation. I noticed that path strings under
Windows required that I double up the backslash "\" as it is used as an
escape character as in C. I think that most if not all of the "Unix tools"
ported to Windows accept path strings with a single backslash. I wonder if
it would be worthwhile to reproduce that behavior under R somehow? I mean
kind of preprocessing the params used as path strings transparently since
character vectors don't "escape" the backslash.

I understand it is much easier to require from users of R under Windows to
comply with it's path strings needs. Maybe it would be nice to just provide
a simple function in "base" for the sole purpose of translating Windows path
strings to the required form.

Just a though.
