Description: Provides HE plot and other functions for visualizing
        hypothesis tests in multivariate linear models. HE plots
        represent sums-of-squares-and-products matrices for linear
        hypotheses and for error using ellipses (in two dimensions) and
        ellipsoids (in three dimensions). It also provides other tools
        for analysis and graphical display of the models such as robust
        methods and homogeneity of variance covariance matrices. The
        related 'candisc' package provides visualizations in a
        reduced-rank canonical discriminant space when there are more
        than a few response variables.
