motif_brokerage {manynet}

Motifs of brokerage

Description

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

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

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

• node_brokering_activity() measures nodes' brokerage activity.

• node_brokering_exclusivity() measures nodes' brokerage exclusivity.

Usage

node_by_brokerage(.data, membership, standardized = FALSE)

net_by_brokerage(.data, membership, standardized = FALSE)

node_brokering_activity(.data, membership)

node_brokering_exclusivity(.data, membership)

node_in_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.
