Plots of the log2 expression ratios (M values) versus the mean log2 expression values (A values) for each probe for each array.

arguments to pass to
The so-called "MA" plot can be used to evaluate whether their is a bias associated with overall intenstity level for each array. Loess smoothed regression lines are superimposed on each plot to demonstrate the trend.
signature(x = "MAList")
A values are stored as matrices in
signature(x = "NChannelSet")
A values are calculated from the
G matrices returned by
densityplot for density plots
of log2 intensity values,
levelplot for pairwise distance
plots between arrays,
MADvsMedianPlot for median
absolute deviation versus median plots.
