These data are from Affy ATH1 array experiments of genomic response to brassinosteroid in Arabidopsis conducted by two laoratories. The data set contains 500 random selected genes and 10 samples, 6 from lab 1 and 4 from lab 2. Data were pre-processed by RMA

arab.gnames |
character vector containing the AffyID of
the 500 genes for the expression matrix |
arab.origin |
numeric vector encoding the origin of the samples, 6 samples from lab 1 (code 1) and 4 samples from lab 2 (code 2) |
