A log-likelihood ratio test for testing whether the sample mena direction is equal to some predefined one.

1 | ```
meandir.test(x, mu, B = 999)
``` |

`x` |
A matrix with the data, unit vectors. |

`mu` |
A unit vector with the hypothesized mean direction. |

`B` |
A number either 1, so no bootstrap calibration is performed or more than 1, so bootstrap calibration is performed. |

The log-likelihood ratio test is performed.

A list including:

`mean.dir` |
The sample mean direction |

`pvalue` |
The p-value of the test. |
