## Canonical Discriminant HE plots

### Description

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.

### Usage

```
## S3 method for class 'candiscList'
heplot(mod, term, ask = interactive(), graphics = TRUE, ...)
```

### Arguments

`mod` |
A |

`term` |
The name of one term to be plotted for the |

`ask` |
If |

`graphics` |
if |

`...` |
Arguments to be passed down |

### Value

No useful value; used for the side-effect of producing canonical HE plots.
