plot.group {agricolae} R Documentation

## Plotting the multiple comparison of means

### Description

It plots bars of the averages of treatments to compare. It uses the objects generated by a procedure of comparison like LSD, HSD, Kruskall, Waller-Duncan, Friedman or Durbin. It can also display the 'average' value over each bar in a bar chart.

### Usage

## S3 method for class 'group'
plot(x,variation=c("range","IQR","SE","SD"), decreasing = TRUE,
horiz=FALSE,col=NULL,xlim=NULL,ylim=NULL,main=NULL,cex=NULL,hy=0,...)


### Arguments

 x Object created by a test of comparison variation in lines by range, IQR, standard deviation or error decreasing Logical, decreasing order of the mean horiz Horizontal or vertical image col line colors xlim optional, axis x limits ylim optional, axis y limits main optional, main title cex optional, group label size hy optional, default =0, sum group label position ... Parameters of the function barplot()

### Details

The output is a vector that indicates the position of the treatments on the coordinate axes.
