rankmatrix {coRanking}

Rank matrix

Description

Replaces the elements of X with their rank in the column vector of the distance matrix

Usage

rankmatrix(X, input = c("data", "dist"), use = "C")

Arguments

X

data, dist object, or distance matrix

input

type of input

use

if 'C' uses the compiled library, else uses the native R code

Details

Each column vector in the distance matrix (or the distance matrix computed from the input) is replaced by a vector indicating the rank of the distance inside that vector.

This is a computation step necessary for the co-ranking matrix and provided mainly so that the user has the possibility to save computation time.

Value
