plot.fem {FisherEM}

The plot function for 'fem' objects.

Description

This function plots different information about 'fem' objects such as model selection, log-likelihood evolution and visualization of the clustered data into the discriminative subspace fitted by the Fisher-EM algorithm.

Usage

 ## S3 method for class 'fem'
plot(x, frame=0, crit=c(),...)

Arguments

frame

0: all plots; 1: selection of the number of groups; 2: log-likelihood; projection of the data into the discriminative subspace.

crit
