### Description

Draws a polygon or a circumference around the center of the Biplot with a proportional radio at the longest distance of the genotype.

### Usage

```
AMMI.contour(model, distance, shape, ...)
```

### Arguments

`model` |
Object |

`distance` |
Circumference radius >0 and <=1 |

`shape` |
Numerical, relating to the shape of the polygon outline. |

`...` |
Parameters corresponding to the R lines function |

### Details

First, it is necessary to execute the AMMI function. It is only valid for the BIPLOT function but not for the TRIPLOT one.

### Value

Distance from genotype to origin (0,0) |
