rarray

Array reconstruction

Produces an array starting from its matricization with all the frontal slices of the array next to each other.

rarray(Xa, n, m, p)

`Xa`	Matrix (or data.frame coerced to a matrix) containing the elements of the frontal slices of an array
`n`	Number of `A`-mode entities
`m`	Number of `B`-mode entities
`p`	Number of `C`-mode entities

`X`	Array leading to `Xa`

Xa <- matrix(1:8,nrow=2)
X <- rarray(Xa, 2, 2, 2)
# original array
