R: Correspondence between classifications

mapClass {mclust} | R Documentation

## Correspondence between classifications

### Description

Best correspondence between classes given two vectors viewed as alternative classifications of the same object.

### Usage

    mapClass(a, b)

### Arguments

`a` | A numeric or character vector of class labels.
`b` | A numeric or character vector of class labels. Must have the same length as `a`.

### Value

A list with two named elements, `aTOb` and `bTOa` which are themselves lists. The `aTOb` list has a component corresponding to each unique element of `a`, which gives the element or elements of `b` that result in the closest class correspondence.

The `bTOa` list has a component corresponding to each unique element of `b`, which gives the element or elements of `a` that result in the closest class correspondence.

### Examples

    a <- rep(1:3, 3)
    a
    b <- rep(c("A", "B", "C"), 3)
    b
    mapClass(a, b)
    a <- sample(1:3, 9, replace = TRUE)
    a
    b <- sample(c("A", "B", "C"), 9, replace = TRUE)
    b
    mapClass(a, b)
