Measure of within-group mixing in networks proposed in Gupta, Anderson and May (1989).
gamix(object, ...)# S3 method for table
gamix(object, ...)
# S3 method for igraph
gamix(object, vattr, ...)
# S3 method for default
gamix(object, ...)
Numerical value of the measure.
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
proportionate mixing.
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.
