Measures of network closure
Description
These functions offer methods for summarising the closure in configurations in one-, two-, and three-mode networks:
-
network_reciprocity()
measures reciprocity in a (usually directed) network. -
node_reciprocity()
measures nodes' reciprocity. -
network_transitivity()
measures transitivity in a network. -
node_transitivity()
measures nodes' transitivity. -
network_equivalency()
measures equivalence or reinforcement in a (usually two-mode) network. -
network_congruency()
measures congruency across two two-mode networks.
Usage
network_reciprocity(.data, method = "default")
node_reciprocity(.data)
network_transitivity(.data)
node_transitivity(.data)
network_equivalency(.data)
network_congruency(.data, object2)
Arguments
.data |
An object of a
|
method |
For reciprocity, either |
object2 |
Optionally, a second (two-mode) matrix, igraph, or tidygraph |
Details
For one-mode networks, shallow wrappers of igraph versions exist via
network_reciprocity
and network_transitivity
.
For two-mode networks, network_equivalency
calculates the proportion of three-paths in the network
that are closed by fourth tie to establish a "shared four-cycle" structure.
For three-mode networks, network_congruency
calculates the proportion of three-paths
spanning two two-mode networks that are closed by a fourth tie to establish a
"congruent four-cycle" structure.
Equivalency
The network_equivalency()
function calculates the Robins and Alexander (2004)
clustering coefficient for two-mode networks.
Note that for weighted two-mode networks, the result is divided by the average tie weight.
