DA.var: Explained variance in Discriminant Analysis

Description

Calculate intergroup variance explained by components of a Discriminant Analysis (either obtained from the function lda) of the package MASS or the function plsda() of the package mixOmics).

Usage

DA.var(model)

Arguments

model

object of class "lda" (from the function lda() of the package MASS) or "plsda" (from the function plsda() of the package mixOmics).

Examples

# LDA model
require(MASS)
data(iris)
model.LDA <- lda(iris[,1:4],iris$Species)
DA.var(model.LDA)

# PLS-DA model
require(mixOmics)
data(yeast)
model.PLSDA <- plsda(t(yeast$data),yeast$strain.cond,ncomp=3)
DA.var(model.PLSDA)
