R: Rank matrix

rankmatrix {coRanking} | R Documentation

## 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

returns a matrix of class `'rankmatrix'`
