     This 'ExpressionSet' object contains a subset of the microarray
     data used in References for *PLGEM* set-up and validation.
     Briefly, it contains normalized gene expression values from a
     total of 6 hybridizations on MG-U74Av2 Affymetrix GeneChip
     microarrays. Two experimental conditions are represented in this
     dataset: the baseline condition (C) contains data of immature
     murine dendritic cells (4 replicates); the other condition (LPS)
     contains data of the same cells stimulated for 4 hours with LPS (2
     replicates).
