You know, let's assume Nu is NOT ignorant. He probably read the warning--just like I did. My guess is that he was asking how to use the Affydata package regardless of the warning--since, you know, its a warning, not an error. When Nu did use 'oligo' he found there were problems.
I have reasons for wanting to use the Affydata package--I don't care what the warning says. If you know how to help, please do; if you don't know how to get past the warning and use the Affy package, then please don't waste our time with your answer.
