Visualizing Hypothesis Tests in Multivariate Linear Models Provides HE plot functions for visualizing hypothesis tests in multivariate linear models. They represents sums-of-squares-and-products matrices for linear hypotheses and for error using ellipses (in two dimensions) and ellipsoids (in three dimensions). Software Depends: R (>= 2.10), car, graphics, stats Suggests: rgl, candisc, effects, reshape, gplots, nlme, lattice, reshape2 Michael Friendly <friendly@yorku.ca> John Fox, Michael Friendly, and Georges Monette GPL (>= 2) 2012-05-17 application/tgz http://CRAN.R-project.org/package=heplots
