%description
Functions for computing and visualizing generalized canonical discriminant
analyses and canonical correlation analysis for a multivariate linear
model. Traditional canonical discriminant analysis is restricted to a
one-way 'MANOVA' design and is equivalent to canonical correlation
analysis between a set of quantitative response variables and a set of
dummy variables coded from the factor variable. The 'candisc' package
generalizes this to higher-way 'MANOVA' designs for all factors in a
multivariate linear model, computing canonical scores and vectors for each
term. The graphic functions provide low-rank (1D, 2D, 3D) visualizations
of terms in an 'mlm' via the 'plot.candisc' and 'heplot.candisc' methods.
Related plots are now provided for canonical correlation analysis when all
predictors are quantitative. Methods for linear discriminant analysis are
now included.
