Censuses of brokerage motifs

Description

These functions include ways to take a census of the brokerage positions of nodes in a network:

• node_brokerage_census() returns the Gould-Fernandez brokerage roles played by nodes in a network.

• network_brokerage_census() returns the Gould-Fernandez brokerage roles in a network.

Usage

node_brokerage_census(.data, membership, standardized = FALSE)

network_brokerage_census(.data, membership, standardized = FALSE)

node_brokering_activity(.data, membership)

node_brokering_exclusivity(.data, membership)

node_brokering(.data, membership)

Arguments

.data

An object of a {manynet}-consistent class:

• matrix (adjacency or incidence) from {base} R

• edgelist, a data frame from {base} R or tibble from {tibble}

• igraph, from the {igraph} package

• network, from the {network} package

• tbl_graph, from the {tidygraph} package

membership

A vector of partition membership as integers.

standardized

Whether the score should be standardized into a z-score indicating how many standard deviations above or below the average the score lies.
