Querying node measures

These functions are a collection of node measures that do not really fall into the class of centrality measures. For lack of a better place they are collected under the node_* umbrella of functions.

Usage
node_eccentricity(mode = "out")

node_constraint(weights = NULL)

node_coreness(mode = "out")

node_diversity(weights = NULL)

node_bridging_score()

node_effective_network_size()

node_connectivity_impact()

node_closeness_impact()

node_fareness_impact()

Arguments
mode

The way edges should be followed in the case of directed graphs.

weights

The weights to use for each node during calculation

Value

A numeric vector of the same length as the number of nodes in the graph.

Functions

  • node_eccentricity: measure the maximum shortest path to all other nodes in the graph

  • node_constraint: measures Burts constraint of the node. See igraph::constraint()

  • node_coreness: measures the coreness of each node. See igraph::coreness()

  • node_diversity: measures the diversity of the node. See igraph::diversity()

  • node_bridging_score: measures Valente's Bridging measures for detecting structural bridges (influenceR)

  • node_effective_network_size: measures Burt's Effective Network Size indicating access to structural holes in the network (influenceR)

  • node_connectivity_impact: measures the impact on connectivity when removing the node (NetSwan)

  • node_closeness_impact: measures the impact on closeness when removing the node (NetSwan)

  • node_fareness_impact: measures the impact on fareness (distance between all node pairs) when removing the node (NetSwan)
