)

Arguments

model

bivariate angular model whose mixture is of interest. Must be one of "vmsin", "vmcos" and "wnorm2".

kappa1, kappa2, kappa3, mu1, mu2, pmix

model parameters and mixing proportions. See the respective mixture model densities (dvmsinmix, dvmcosmix, dwnorm2mix) for more details.

xpoints

Points on the first (x-) coordinate where the density is to be evaluated. Default to seq(0, 2*pi, length.out=100).

ypoints

Points on the first (x-) coordinate where the density is to be evaluated. Default to seq(0, 2*pi, length.out=100).

levels

numeric vector of levels at which to draw contour lines; passed to the contour function in graphics.

nlevels

number of contour levels desired if levels is not supplied; passed to the contour function in graphics.

xlab, ylab, col, lty, main

graphical parameters passed to contour.
