R-helpers: 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? --j -- Jonathan A.

What is wrong with
winpath <- readLines("clipboard ")
?
If you want to show that as a literal in your code, then don't bother
assigning it to a variable, but let it echo to output and copy THAT and put it
in your source code.
There is also file.choose()...
