⚠️There's a newer version (1.7.3) of this package.Take me there.

heplots (version 1.3-8)

Visualizing Hypothesis Tests in Multivariate Linear Models

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). The related 'candisc' package provides visualizations in a reduced-rank canonical discriminant space when there are more than a few response variables.
