ternary

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.
