example exprSet instance

Description

This data set is a small excerp from an Affymetrix hgu133plus2 microarray experiment. It contains 8 chips from 4 patients, 2 B-cell-ALL (acute lymphoblastic leukemia) and 2 T-cell-ALL patients. Two samples per patient were hybridized onto the chips, one before treatment and one after 6 hours GC (glucocorticoid) treatment. From every Affymetrix GeneChip only 1000 probe sets are included in this small dataset. \ For further informations and examples refer to the package vignette (which can be opened using the openMadbVignette).
