ternary {StatDA} | R Documentation

## Ternary plot

### Description

This plot shows the relative proportions of three variables in one diagramm. It is important that the proportion sum up to 100% and if the values of the variables are very different it is important to scale them to the same data range.

### Usage

    ternary(x, nam = NULL, grid = FALSE, ...)

### Arguments

`x` | matrix with 3 columns
`nam` | names of the variables
`grid` | if TRUE the grid should be plotted
`...` | further graphical parameters, see par

### Details

The relative proportion of each variable is computed and those points are plotted into the graphic.
