[BioC] Re-scaling MA plot Y axis in LimmaGUI?

I'm checking what you say. The resize Window only adjusts the scale of
the whole plot window, not the scale on either axis.
There isn't a way of adjusting the scales on the axis in limmaGUI,
though it is being considered as a future modification.
If an M value is not being plotted, try a different background
correction method. The Subtract method(the default in limmaGUI) may
produce some negative values, which are hence excluded. Use None
instead. There will soon be a change to limmaGUI that includes the
normexp algorithm which is currently available in limma.
Your right about the command line limma program - more features are
currently available using it. We plan to add more features to the GUI
programs. Your comments on which ones (other than settable scale
parameters) are welcome.
