Description

Converts between permutation vectors and matrices.

Usage

permutation_vector2matrix(x)

permutation_matrix2vector(x)

Arguments

x	A permutation vector (any object that can be converted into a permutation vector, e.g., a integer vector or a hclust object) or a matrix representing a permutation. Arguments are checked.
