mapClass: Correspondence between classifications

In mclust: Gaussian Mixture Modelling for Model-Based Clustering, Classification, and Density Estimation

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.

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