Contour lines are produced of mixture model for spherical data only.
A two column matrix. The first column is the longitude and the second is the latitude.
This is mix.vmf object. Run a mixture model and save it as mod for example, mod = mix.vmf(x, 3).
The contour plot is displayed with latitude and longitude in the axes. No Lambert projection is used here. This works for spherical data only which are given as longitude and latitude.
A plot including: The points and the contour lines.
