[R] Trying to avoid a loop

Although I could write a loop to do the following, I would like
to avoid this as it would be expensive.  Does anyone know if
there is an R function that would make this faster?

Given a 3 dimensional array, say Z with dimensions {n,l,k},  I would
like to create a matrix Y with dimensions {n,l}, each element of which
contains the position {k} with the largest element that dimension.

Many thanks,
Michael Roberts
