heplot.candiscList {candisc} | R Documentation |
These functions plot ellipses (or ellipsoids in 3D) in canonical discriminant space representing the hypothesis and error sums-of-squares-and-products matrices for terms in a multivariate linear model. They provide a low-rank 2D (or 3D) view of the effects for that term in the space of maximum discrimination.
## S3 method for class 'candiscList': heplot(mod, term, ask = interactive(), graphics = TRUE, ...) ## S3 method for class 'candiscList': heplot3d(mod, term, ask = interactive(), graphics = TRUE, ...)
mod |
A candiscList object for terms in a mlm |
term |
The name of one term to be plotted for the heplot and
heplot3d methods. If not specified, one
plot is produced for each term in the mlm object. |
ask |
If TRUE (the default), a menu of terms is presented; if ask is FALSE,
canonical HE plots for all terms are produced. |
graphics |
if TRUE (the default, when running interactively), then the menu of terms to plot is presented in a dialog box rather than as a text menu. |
... |
Arguments to be passed down |
No useful value; used for the side-effect of producing canonical HE plots.
