`x`	a three-dimensional `array` of matrices
`na.last`	for controlling the treatment of `NA`s. If `TRUE`, missing values in the data are put last; if `FALSE`, they are put first; if `NA`, they are removed; if `"keep"` they are kept with rank `NA`.
`ties.method`	a character string specifying how ties are treated, see ‘Details’; can be abbreviated.
