[BioC] Stange message with getOption("device") in OSX

[Florian Hahne]

Hi Gonzalo,
how about using dev.new():
'dev.new' opens a new device.  Normally R will open a new device
      automatically when needed, but this enables you to open further
      devices in a platform-independent way.  (For which device is used
      see 'getOption("device")'.)
