[BioC] some problem of dir.create()

[Kasper Daniel Hansen]

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.
