[R] Checking existance of a directory

[Andris Jankevics]

Hi, something like this perhaps,

 if("myfolder"%in%dir()==FALSE) dir.create("myfolder")

Command dir.create() is not overwriting an existing folder.

Best regards,
Andris

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.
