mixnorm.contour

Contour plot of the Gaussian mixture model in S^2

Contour plot of the Gaussian mixture model in S^2.

mixnorm.contour(x, mod)

`x`	A matrix with the compositional data.
`mod`	An object containing the output of a `mix.compnorm` model.

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

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