dmatrix {socialh}

Sij dyadic relationship matrix

Description

Function to obtain the Sij dyadic dominance relationship from an sociomatrix.

Usage

dmatrix(smatrix)

Arguments

smatrix

sociomatrix

Details

The dyadic relationship is obtained by the following expression: Sij = (Xij - Xji) / (|Xij - Xji|), where Sij is the social status of the ith animal relative to the jth animal; Xij is the number of times the animal i won the animal j; Xji is the number of times the animal j won the animal i.

Value

Dyadic matrix
