dyad_triad_table: Forbidden triad table

In anespinosa/netmem: Social Network Measures using Matrices

Forbidden triad table

Description

This function explores dyads and triads (Simmel, 1950), building from the 'forbidden triad' (Granovetter, 1973). First, the minimum structure is an isolated node, then dyads. Afterwards, different combinations of 'forbidden triads' are explored.

Usage

dyad_triad_table(A, adjacency_list = FALSE, min = NULL, max = NULL)

Arguments

A	A symmetric matrix object.
adjacency_list	Whether to return the adjacency list of triads 201 per node.
min	Numeric constant, lower limit on the size of the triads 201 to find. NULL means no limit, ie. it is the same as 0.
max	Numeric constant, upper limit on the size of the triads 201 to find. NULL means no limit.

Value

This function return the list of triads that each node belong.

If adjacency_list = TRUE it also return the adjacency list of the 'forbidden triads' per node.
