Sometimes, you don't find an(other) answer because you already have
one... ;-)
In this case,
gsub('/', '\\\\', 'c:/dir1/dir2/file.ext')
actually does what you want. Notice that print doesn't just dump the
string, it renders it in a representation suitable for the righthand
side in an R assignment. You could convince yourself with
cat(gsub('/', '\\\\', 'c:/dir1/dir2/file.ext'))
which actually does dump the string.
