Description

Restore an array from its matricization with all the frontal slices of the array next to each other (mode="A")

Usage

toArray(x, n, m, r, mode = c("A", "B", "C"))

Arguments

x	Matrix (or data.frame coerced to a matrix) containing the elements of the frontal slices of an array
n	number of A-mode elements
m	number of B-mode elements
r	number of C-mode elements
mode	in which mode is the matricized array
