AMMI.contour: AMMI contour

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

shape

Numerical, relating to the shape of the polygon outline.

...

Parameters corresponding to the R lines function

Value

• model
  output AMMI
• distance
  Numeric >0 and <=1< description="">
• shape
  Numeric

Details

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