Found an obsolete/platform-specific call in the following functions:
  'superpc.plot.lrtest' 'superpc.plotcv' 'superpc.plotred.lrtest'
  'superpc.predictionplot' 'superpc.rainbowplot'
Found the platform-specific device:
  'win.metafile'
dev.new() is the preferred way to open a new device, in the unlikely
event one is needed.
