The second syntax is correct:
> gsub('/', '\\\\', 'c:/dir1/dir2/file.ext')
[1] "c:\\dir1\\dir2\\file.ext"Indeed, R escapes backslashes. That is why they are doubled in R strings. However, they appear as single backslashes in oyur text file:
> res <- gsub('/', '\\\\', 'c:/dir1/dir2/file.ext')
> cat(res, file = "test.txt")
> file.show("test.txt", delete.file = TRUE)You got this in your file:
c:\dir1\dir2\file.ext
thus pretty readable by a Windows app. Best,

Dear R-helpers
I am running R2.0.0 under Windows 2000. I am compiling a number of file paths into a simple text file that will be read by some other software we use. Unfortunately, it can only handle file paths with back slashes (MS Windows convention), and from R, I get file paths with forward slashes. The following didn't work.
gsub('/', '\\', 'c:/dir1/dir2/file.ext')
[1] "c:dir1dir2file.ext"
gsub('/', '\\\\', 'c:/dir1/dir2/file.ext')
[1] "c:\\dir1\\dir2\\file.ext"
I have tried to find an answer on R-help, but didn't ;-(
Thanks for helping me, Kind regards, J�rg
