Thanks, Jim and Dan! To Jim: Yes, I tried capabilities and there are TRUEs under png as well as jpeg, so changing dev to other format didn't work. I also noticed that there's a FALSE under X11. Another post https://stat.ethz.ch/pipermail/bioconductor/2006-August/014161.html mentioned that png needs X11 to be running. But seems now MAC doesn't support X11 any more. To Dan: Yes, I was running the code from the beginning of that chapter. AnnBuilder is indeed obsolete, but the book mentioned that the data set beta 7 can alternatively be loaded from the data package beta7, which is what I did and it was successful. So I guess the problem may be related to the maQualityPlots function and the MAC system themselves. >>> Dan Tenenbaum 01/03/13 12:50 PM >>> On Thu, Jan 3, 2013 at 8:37 AM, James W.

I am guessing that you are working your way through this code: http://www.bioconductor.org/help/publications/books/bioinformatics- and-computational-biology-solutions/chapter-code/TwoColorPre.R This uses packages which are obsolete so it's not surprising that you are getting errors.
