Using apply for two datasets
Thanks a lot for the quick help! mapply() seems promising. However, mapply(t.test, myData1, myData2) would not work, so how can I specify the margin in mapply() which function t.test() will be applied over? For example, I specify the 2nd dimension (column) in apply(myData1, 2, t.test) to run one-sample t-test. Is there a way I can achieve the same with mapply()? Thanks again, Gang

I think that you can use mapply for this. On Tue, Jan 6, 2009 at 3:24 PM, Gang Chen <gangchen6 at gmail.com> wrote:
I can run one-sample t-test on an array, for example a matrix myData1, with the following apply(myData1, 2, t.test) Is there a similar fashion using apply() or something else to run 2-sample t-test with datasets from two groups, myData1 and myData2, without looping? TIA, Gang
