The expression data are real but anonymized. The data are from an experiment
that used Affymetrix U95v2 chips. The data were processed by dChip and then
exported to R for analysis. The data illustrate ExpressionSet-class, with
assayData containing the required matrix element exprs and an additional matrix
se.exprs. se.exprs has the same dimensions as exprs. The phenoData and
standard error estimates (se.exprs) are made up. The information in
the "description" slot is fake.
