Measure of within-group mixing in networks proposed in Gupta, Anderson and May (1989).
gamix(object, ...) ## S3 method for class 'table' gamix(object, ...) ## S3 method for class 'igraph' gamix(object, vattr, ...) ## Default S3 method: gamix(object, ...)
R object, see Details for available methods
other objects passed to/from other methods
character, name of vertex attribute
The measure varies between
-1/vcount(g) for dissassortative mixing
and 1 for perfect within-group mixing. It takes a value of 0 for
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
cross-classyfying all dyads, in which
h correspond to
group membership of ego and alter respectively. Layers
y=2 are assumed to be non-contact and contact layers respectively.
object is of class "igraph" it is required to supply
with the name of the vertex attribute to calculate intermediate mixing
Numerical value of the measure.
