[R] Avoiding loops & apply -function

[David Masson]

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,,])
    }


-  "E" is a 3-dimensional array filled with a given data X.
-  "data" is a (nlon*nlat) matrix filled with given data Y.
-  "G" is my output vector.

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


Thanks for your help!
