Categorical Principal Component Analysis

Usage

CATPCA(bp, dim.biplot = c(2, 1, 3), e.vects = 1:ncol(bp$X),
group.aes = NULL, show.class.means = FALSE)

bp: an object of class biplot obtained from preceding function biplot().
dim.biplot: dimension of the biplot. Only values 1, 2 and 3 are accepted, with default 2.
e.vects: which eigenvectors (principal components) to extract, with default 1:dim.biplot.
group.aes: vector of the same length as the number of rows in the data matrix for differentiated aesthetics for samples.
show.class.means: logical, indicating whether group means should be plotted in the biplot.
