Also, file.path() does not make sure in any way that the path actually exists on your system. Essentially it is equivalent to paste(baseDir, GEO, sep = "/") You could f.eks. try file.exists(file.path(baseDir, GEO)) As Martin said: your problem is that when you create the directory (by using dir.create()) you do not give it the full path name.
