WebValue. If each call to FUN returns a vector of length n, then apply returns an array of dimension c (n, dim (X) [MARGIN]) if n > 1. If n equals 1, apply returns a vector if MARGIN has length 1 and an array of dimension dim (X) [MARGIN] otherwise. If n is 0, the result has length 0 but not necessarily the ‘correct’ dimension.
