R: PLOT AMMI

plot.AMMI {agricolae} | R Documentation

## PLOT AMMI

### Description

Biplot AMMI.

### Usage

    ## S3 method for class 'AMMI'
    plot(x,first=1,second=2,third=3,type=1,number=FALSE,gcol=NULL,ecol=NULL,
    icol=NULL,angle=25,lwd=1.8,length=0.1,xlab=NULL,ylab=NULL,xlim=NULL,ylim=NULL,...)

### Arguments

`x` | object AMMI
`first` | position axis x, 0=Y-dependent, 1=PC1, 2=PC2, 3=PC3
`second` | position axis y,0=Y-dependent, 1=PC1, 2=PC2, 3=PC3
`third` | position axis z,0=Y-dependent, 1=PC1, 2=PC2, 3=PC3
`type` | 1=biplot, 2= triplot 3=influence genotype
`number` | TRUE or FALSE names or number genotypes
`gcol` | genotype color
`ecol` | environment color
`icol` | influence color
`angle` | angle from the shaft of the arrow to the edge of the arrow head
`lwd` | parameter line width in function arrow
`length` | parameter length in function arrow
`xlab` | x labels
`ylab` | y labels
`xlim` | x limites
`ylim` | y limites
`...` | other parameters of plot

### Details

type=1 produce graphs biplot. type=2 produce graphs triplot, the components are normalizad in scale 0-1. type=3 produce graphs on a 2d point set that are all subgraphs of the Delaunay triangulation. The Gabriel graph is a subgraph of the delaunay triangulation and has the relative neighbor graph as a sub-graph.

### Examples

    library(agricolae)
    data(plrv)
    model<- with(plrv,AMMI(Locality, Genotype, Rep, Yield))
    # biplot PC2 vs PC1
    plot(model)
    ## plot PC1 vs Yield
    plot(model,0,1,gcol="blue",ecol="green")
    ## triplot PC 2,3,4
    if (requireNamespace("klaR", quietly = TRUE)) {
    plot(model,first=2,second=3,third=4, type=2,number=TRUE)
    }
    # biplot with influence genotype in pc3 vs pc2
    if (requireNamespace("spdep", quietly = TRUE)) {
    plot(model,first=2,second=3, type=3,number=TRUE,icol="green")
    }
