[R] Apply and its friends

[Crispin Miller]

Hi,
Forgive a very basic question...
I need to take two lists-of-lists, and apply a function to each pair of elements in the lists  to return a single list...
For example

l1 <- list(1:5,6:10,2:15)
l2 <- list(1:8,4:12,1:19,4:20)

I could easily do an lapply across each of them, but is there a function that does a sort-of pairwise-apply across both together?

Does anybody know of a good document that discusses this kind of basic matrix/list/vector manipulation in R?
Regards,
crispin
