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