Colemans's homphily index for directed networks.

```
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, ...)
```

`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 |

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.
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.

Vector of numeric values of the index for each group
