BIC to choose the number of components in a model based clustering using mixtures of von Mises-Fisher distributions

1 | ```
bic.mixvmf(x, A, n.start = 20)
``` |

`x` |
A matrix containing directional data. |

`A` |
The maximum number of clusters to be tested. Default value is 3. |

`n.start` |
The number of random starts to try. See also R's built-in function |

If the data are not unit vectors, they are transformed into unit vectors.

A list including:

`BIC` |
The BIC values for all the models tested. |

`A plot` |
A plot of the BIC values. |

`runtime` |
The run time of the algorithm. A numeric vector. The first element is the user time, the second element is the system time and the third element is the elapsed time. |
