R help - May 2006 - changing single to double backslash

Hi, all. I didn't find something like this in the faq
list:

I wound like build a function to substitute single
backslashes in a string to double:
ChangeSlash<-function(dir) ...

so

ChangeSlash("C:\mydocs\test")

returns

"C:\\mydocs\\test"

Thanks,
C.

Well, the FAQ and the rw-FAQ suggest that you need to use doubled 
backslashes when entering the string.

This is not possible: "C:\mydocs\test" is parsed with \t indicating a
tab
and \m indicating m.
