slice.index(x, MARGIN)


x an array. If x has no dimension attribute, it is considered a one-dimensional array.
MARGIN an integer giving the dimension number to slice by.


An integer array y with dimensions corresponding to those of x such that all elements of slice number i with respect to dimension MARGIN have value i.

row and col for determining row and column indexes; in fact, these are special cases of slice.index corresponding to MARGIN equal to 1 and 2, respectively when x is a matrix.


x <- array(1 : 24, c(2, 3, 4))
