Hi,
I am trying to understand the diagnostic plot of the MAD pairwise
differences of the M-values and how this plot can detect outliers.
I looked at the example for the CLL data and did not detect any
differences, but would like to know how to detect any differences.
All the small boxes are different colors but are mirrored pairwise 
intensities.   The notes say:  "Arrays whose distance matrix entries
are way different give cause for suspicion".  However, the color 
intensities look different??  Please explain how to know if they
are "way different".
