Hi all! I don?t know where, but I remember having seen an image of several MvA plots of a number of chips on the same picture. I know that to plot an MvA plot of one chip with a fitted line I should do something like > plot(ma, slide=1,main="MvA plot") > lowessCurve(ma) But what should I write if I want to get MvA plots of my 10 slides on the same figure? I have looked for an answer on the web, but can?t find anything. Any help would be much appreciated. Regards David

Look at the help file for mva.pairs in the affy library. This will do what you want. Jim James W. MacDonald UMCCC Microarray Core Facility 1500 E.

But try par(mfrow=c(5,2)) and then give your plot commands again. Gordon >I have looked for an answer on the web, but can?t find anything.
