It's usually standard to provide an example of what code you've tried
and also to put your data in a form that can be more easily
cut-and-pasted into R.
That said, would something like this work if you know you only have
two sorts of cross in each level?
lapply(spl, function(x) {x <- split(x[,1],x[,2]); t.test(x[[1]], x[[2]])})
