AMMI.contour: AMMI contour

In agricolae: Statistical Procedures for Agricultural Research

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 <=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

Genotypes within and outside the area.

distance

Distance from genotype to origin (0,0)

Note
