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
mix.compnorm.contour(mod, type = "alr", n = 100, x = NULL, cont.line = FALSE)
Arguments
mod
An object containing the output of a mix.compnorm model.
type
The type of trasformation used, either the additive log-ratio ("alr"), the isometric log-ratio
("ilr") or the pivot coordinate ("pivot") transformation.
n
The number of grid points to consider over which the density is calculated.
x
A matrix with the compositional data.
cont.line
Do you want the contour lines to appear? If yes, set this TRUE.
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 (fitted) model.
