`dataset` |
An object of class |

`ry` |
Character string. Name of the outcome in the data set. |

`rmet` |
Character string. Name of the method variable in the data set. |

`rtime` |
Character string. Name of the time variable in the data set. |

`Dmat` |
Matrix of weights. |

`delta` |
Power of the differences. A value of 0 provides an estimate that is comparable to a repeated measures version of kappa index. |

`cl` |
Confidence level. |

A vector that includes the point estimate, confidence interval and standard error of the CCC. Additionally the Fisher's Z-transformation value and its standard error are also provided.
