Description

Details

This function replicates the functionality of the reshape() function on Matlab. This function is basically a fancy wrapper for the array() function in R, but is useful because it saves the user translation time. Moreover, it introduces validation code that alter the behavior of array() and makes it more similar to replicate().

Examples

mx <- matrix(1:4, 2)
ra <- array(1:12, c(2, 3, 2))

mx
reshape(mx, c(1, 4))

ra
reshape(ra, c(3, 2, 2))
