# orwg: Odds ratio of existence of within-group ties In netseg: Measures of Network Segregation and Homophily

## Description

Odds ratio for connected, as opposed to disconnected, dyads depending whether it is between- or within-group, i.e. how much more likely the dyad will be connected if it is within-group.

## Usage

 ``` 1 2 3 4 5 6 7 8 9 10``` ```orwg(object, ...) ## S3 method for class 'table' orwg(object, ...) ## S3 method for class 'igraph' orwg(object, vattr, ...) ## Default S3 method: orwg(object, ...) ```

## Arguments

 `object` R object, see Details for available methods `...` other arguments passed to/from other methods `vattr` character scalar or any vector, name of the vertex attribute or the attribute itself (as a vector)

## Details

The measure takes values, like all odds ratios, from (0; Inf).

If `object` is a table it is interpreted as a mixing matrix. Two-dimensional table is interpreted as a contact layer. Three-dimensional table is interpreted as a full mixing matrix m[ghy] cross-classyfying all dyads, in which g and h correspond to group membership of ego and alter respectively. Layers y=1 and y=2 are assumed to be non-contact and contact layers respectively.

If `object` is of class "igraph" it is required to supply `vattr` with the name of the vertex attribute to calculate intermediate mixing matrix.

## Value

Numeric value of the measure.
