[R] Avoiding loops & apply -function

I have a question concerning avoiding loops. I know the function "apply" and I have used it several times, but I feel blocked
with this situation :

E <- array(X, dim = c(L,nlon,nlat) )
data <- matrix(Y, nrow=nlon, ncol=nlat ) G <- vector(length=L)

   for (l in 1:L)
    {
      G[l] <- function.F(data,E[l,,])
    }

I want to apply the function "function.F", but this function has an argument that depends
on the index "l" ...

Thanks for your help!

David
