Jon and Spencer, First of all, thanks for your insightful comments on my questions. I am quite impressed by the level of support one finds in the r-help mailing list. In particular, as Spencer pointed out in another post, I did not do my homework and you have been overly kind in discussing the issue. I promised Spencer privately that I will read the Posting Guide before getting farther in the thread, but I would like just to give a short answer:

Yes, I intend to do the test across subjects and subject variance is indeed an issue in my case. Thanks for your further suggestions, I will look at them carefully. -- Rafael ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
