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? TIA, Gang
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. -- Bert Gunter -----Original Message----- From: r-help-bounces at r-project.org [mailto:r-help-bounces at r-project.org] On Behalf Of Gang Chen Sent: Thursday, October 02, 2008 11:24 AM To: r-help at stat.math.ethz.ch Subject: [R] t.test() on a list I have a list, myList, with each of its 9 components being a 15X15 matrix.
