Hello, I would like to read 5 experiments in R, and afterwards 1. Exp. with Exp2-14 in MAplot represent. data.raw <- ReadAffy(filenames="./R/ME_cel/Expt1_R1.CEL", "./R/ME_cel/Expt2_R1.CEL", "./R/ME_cel/Expt3_R1.CEL", "./R/ME_cel/Expt4_R1.CEL", "./R/ME_cel/Expt5_R1.CEL") MAplot(data.raw) I cannot get expected representation in ma.plot (limma), mva.pairs and in MAplot can I not use a Set of experiments into a diagram. What can I do? Thanks, Mohammad Esad-Djou
