grecip: Compute the Reciprocity of an Input Graph or Graph Stack

Description

grecip calculates the dyadic reciprocity of the elements of dat selected by g.

Usage

grecip(dat, g=NULL)

Arguments

dat

An adjacency matrix, or stack thereof

g

A vector indicating which matrices to evaluate (optional)

Value

• The graph reciprocity value(s)

Details

The dyadic reciprocity of a graph is the proportion of dyads which are symmetric; this is computed and returned by grecip for the graphs indicated. Note that the dyadic reciprocity is distinct from the tie reciprocity, which is the proportion of edges which are reciprocated.
