I am sure you will get helpful answers. I am almost as sure that you
shouldn't be doing this. I suggest you consult with your local statistician.

Subject: [R] t.test() on a list

I have a list, myList, with each of its 9 components being a 15X15
matrix. I want to run a t-test across the list for each component in
the matrix. For example, the first t-test is on myList[[1]][1, 1],
myList[[2]][1, 1], ..., myList[[9]][1, 1]; and there are totally 15X15
t-tests. How can I run these t-tests in a simple way?
