[R] Ignore escape characters in a string...

One of the minor irritations I have is copying paths from Windows
explorer, which look like:

C:\Program Files\R\R-3.0.3

and using them in a setwd() statement, since the "\" is, of course,
interpreted as an escape character.  I have to, at present, manually
add in the double slashes or reverse them.

So, I'd like to write a quick function that takes this path:

winpath <- "C:\Program Files\R\R-3.0.3"

and converts it to a ready-to-go R path -- is there a way to have R
IGNORE escape characters in a character vector?

Alternatively, is there some trick to using a copy/paste from Windows
explorer I'm not aware of?
