If you type "apply" (no ()) you will find that it is not much more than an
decorated generic loop. I believe that this is case where using a loop.
Otherwise, you could convert you matrix to a data frame, add the degrees of
freedom.... too much work for a loop where plotting anyway has the largest
overhead.
Others may disagree, but I believe the apply-wars have ended at the time
when browser wars ended.
