Has anyone implemented a t-test with the effective sample size correction proposed by Dale and Fortin, Ecoscience 9(2):162-167, 2002, using a discussion by Cressie, 1993, page 15? thanks, Denis

Dear all, When defining explicit keys with xyplot, I have previously used the fill parameter to set the background colour of point symbols. That's no longer working for me, and I am wondering whether it's a bug or whether I've misinterpreted the documentation and have been relying on a feature wasn't intended. If the latter, can anyone suggest the correct way to do it?

Hi Now a more theoretical question. I have two correlation matrices - one of a set of variables under a particular condition, the other of the same set of variables under a different condition. Is there a statistical test I can use to see if these correlation matrices are "different"? Thanks Mick
