## Contourplot for bivariate angular mixture model densities

### Description

Contourplot for bivariate angular mixture model densities

### Usage

```
contour_model(
model = "vmsin",
kappa1,
kappa2,
kappa3,
mu1,
mu2,
pmix = rep(1/length(kappa1), length(kappa1)),
xpoints = seq(0, 2 * pi, length.out = 100),
ypoints = seq(0, 2 * pi, length.out = 100),
levels,
nlevels = 20,
xlab = "x",
ylab = "y",
col = "black",
lty = 1,
main,
...
)
```

### 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 |

`xlab` , `ylab` , `col` , `lty` , `main` |
graphical parameters passed to contour. |

`...` |
additional model specific argment |

### Examples

```
contour_model('vmsin', 1, 1, 1.5, pi, pi)
contour_model('vmcos', 1, 1, 1.5, pi, pi)
```
