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.
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)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
A vector of partition membership as integers.
Whether the score should be standardized into a z-score indicating how many standard deviations above or below the average the score lies.
