Compositional (version 2.2)

Contour plot of a Gaussian mixture model in S^2: Contour plot of a Gaussian mixture model in $S^2$

Description

Contour plot of a Gaussian mixture model in $S^2$.

Usage

mixnorm.contour(x, mod)

Arguments

x

A matrix with the compositional data.

mod

An object containing the output of a mix.compnorm model.

Value

A ternary plot with the data and the contour lines of the fitted Gaussian mixture model.

Details

The contour plot of a Gaussian mixture model is plotted. For this you need the data and the fitted model.
