AMMI.contour {agricolae} | R Documentation

## 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)

    Yield <- sinRepAmmi$YLD
    REP <- 3
    MSerror <- 93.24224
    model<-AMMI(Environment, Genotype, REP, Yield, MSerror)
    plot(model)
    AMMI.contour(model,distance=0.7,shape=8,col="red",lwd=2,lty=5)
