Subject: [R] Using lapply with two lists


Hello guys, 
I have a list L1 of matrix. I have another list L2 with the same number
of
elements representing the row of the L matrix that I want to delete
(L1[[i]][-L2[[i]],]) but I can't do this with lapply as it iterates
through
L1 (first argument) and not L2. Any idea?
