Hi all, I am wondering is there any way to check whether some Directory exists or not, given the parent path of that directory? After searching for a while I found that there is a function dir.create() to create some directory. However I need to know whether such directory already exists or not, otherwise I will create that.
Well, as others have also pointed out, you don't need to do that (and I created dir.create() deliberately so you don't).
But see ?file_test and op = "-d" if you actually need to in some other application. (This is linked from ?file.exists which is linked from ?dir.create.)
? Thanks,
