Contour plot of the Gaussian mixture model in S^2: Contour plot of the Gaussian mixture model in \(S^2\)
Description
Contour plot of the Gaussian mixture model in \(S^2\).
Usage
mixnorm.contour(x, type = "alr", mod)
Arguments
x
A matrix with the compositional data.
type
The type of trasformation used, either the additive log-ratio ("alr"), the isometric log-ratio ("ilr") or the
pivot coordinate ("pivot") transformation.
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.
