It's been a long time since I processed array data and I could really do with some advise for resolving this error.
Thanks for clarifying, Matthew. It is working, indeed. Flawlessly. Haven't tried with the exon arrays, though. Will it still work?
Yes, it will work for exon arrays as well. However, you need to use the oligo package (rather than the affy package) to read in the CEL files.
