getOrderedMatrix | R Documentation |

Function to order the observed matrix of dyadic dominance encounters according to the individuals' NormDS values.

getOrderedMatrix(X, names=NULL, method=c("Dij","Pij"))

`X` |
Empirical sociomatrix containing wins-losses frequencies in dyadic encounters. |

`names` |
Character vector with the names of individuals. This vector is NULL by default |

`method` |
A character string indicating which dyadic dominance measure is to be used for the computation of David's scores. One of "Dij" or "Pij", can be abbreviated. |

`getOrderedMatrix`

is only applied for square matrices in which the set of *n* actors is also the set of *n* partners. The matrices must also be numeric.

`ordered.matrix` |
Matrix of observed dyadic dominance encounters ordered according to the individuals' NormDS values. |

`ordered.names` |
Vector of individuals' names ordered according to their NormDS values. |

`order.seq` |
Sequence used in the order of the matrix of dyadic encounters and the vector of names. |
