Anova for circular data | R Documentation |

Analysis of variance for circular data.

```
hcf.circaov(u, ina)
lr.circaov(u, ina)
het.circaov(u, ina)
embed.circaov(u, ina)
```

`u` |
A numeric vector containing the data that are expressed in rads. |

`ina` |
A numerical or factor variable indicating the group of each value. |

The high concentration (hcf.circaov), log-likelihood ratio (lr.circaov), embedding approach (embed.circaov) or the non equal concentration parameters approach (het.circaov) is used.

A vector including:

`test` |
The value of the test statistic. |

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

`kapa` |
The concentration parameter based on all the data. If the het.circaov is used this argument is not returned. |
