Description Usage Format References Examples
This dose-response microarray data contains 1000 genes and 6 doses (0=control, 0.01, 0.04, 0.16, 0.63, 2.5mg/kg) with 4-5 arrays at each dose level.

An ExpressionSet object, the assayData has 1000 features and 26 samples, and in phenoData contains information of sample names and dose levels.
For the gene expression matrix obtained using the expres function, the column names are (X1, X2, ..., X26). These correspond to the dose levels (obtained using pData function): 0, 0, 0.01, 0.01, 0.04, 0.04, 0.16, 0.16, 0.63, 0.63, 2.50, 2.50, 0, 0, 0, 0.01, 0.01, 0.01, 0.04, 0.04, 0.16, 0.16, 0.63, 0.63, 2.50, 2.50.
