coleman: Coleman's homophily index

In mbojan/isnar: Introduction to Social Network Analysis with R

Description

Colemans's homphily index for directed networks.

Usage

coleman(object, ...)

## S3 method for class 'table'
coleman(object, gsizes = NULL, loops = FALSE, ...)

## S3 method for class 'igraph'
coleman(object, vattr, ...)

## Default S3 method:
coleman(object, ...)

Arguments

object	R object, see Details for available methods
...	other arguments passed to/from methods
gsizes	numeric vector of group sizes
loops	logical, whether loops are allowed
vattr	character, vertex attribute

Details

Coleman's homophily index computes homophily scores for each group defined by a vertex attribute.

If object is a table it is interpreted as a mixing matrix. If it is only the contact layer (2-dimensional), then vector of group sizes need to be supplied via gsizes.

object can be of class "igraph"

Default method tries to coerce object to table and use other methods.

Value

Vector of numeric values of the index for each group
