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")
Avalues are stored as matrices in
signature(x = "NChannelSet")
Avalues are calculated from the
Gmatrices 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.
