Hello, 

I uses hgu133.csv (e.g. http://affycomp.biostat.jhsph.edu/AFFY2/rafa@jhu.edu/030424.1033/ [http://affycomp.biostat.jhsph.edu/AFFY2/rafa@jhu.edu/030424.1033/] by Rafael A. Irizarry) with affycomp package. 

I can use 

>affycompPlot(rma.assessment$MA) 

correctly. But now I want to produce 'ma.plot' only for 42 Spike-in genes (not 22300 genes) and only 3 rep. (e.g. CEL 1 Rep 1, 2, 3). is this possible in affycomp package? 

I achieved my goal directly with R, but I would like to know whether also in affycomp is realized. 

Thanks,

Mohammad Esad-Djou
