[BioC] MAplot

[Mohammad Esad-Djou]

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
