R 2.7.2
Windows XP
I am using apply to compute a series of Student's t-test from two matrices,
sample1 and sample2.
boo<-apply(sample1,1,t.test,sample2)
I want to pick of the p-values from the tests, but can't seem to get it to
work. I have tried several methods to get the values including:
boo<-apply(sample1,1,t.test$t.test,sample2)
boo<-apply(sample1,1,t.test,sample2)$t.test
any suggestions?
Thanks
John
