targbetween_alldyads: Targeted Betweenness Centrality for Specified Source and...

In bcbritt/targbetween: Targeted Betweenness Centrality

Description

This function computes targeted betweenness centrality for one or more sources and one or more destinations. The set of dyads to be evaluated includes all possible pairs of source vertices and destination vertices from the specified source and destination vectors.

Usage

targbetween_alldyads(
  network,
  source,
  destination,
  filename = NULL,
  directed = FALSE,
  update = 0
)

Arguments

network	An igraph network graph
source	A vector of one or more vertices in network
destination	A vector of one or more vertices in network
filename	A character value indicating the file location to output results (default = NULL)
directed	A boolean value indicating whether the network should be treated as directed (default = FALSE)
update	A numeric value indicating how many loop iterations should elapse between progress updates (default = 0, which suppresses output)

Value

A data.frame with the results for targeted betweenness centrality

Examples

my_network <- igraph::erdos.renyi.game(20, 0.5, directed = FALSE)
single_source <- igraph::V(my_network)[1]
single_destination <- igraph::V(my_network)[20]
multiple_sources <- igraph::V(my_network)[1:5]
multiple_destinations <- igraph::V(my_network)[6:10]
results1 <- targbetween_alldyads(my_network, single_source,
  single_destination)
results2 <- targbetween_alldyads(my_network, single_source,
  multiple_destinations, directed=FALSE)
results3 <- targbetween_alldyads(my_network, multiple_sources,
  single_destination, directed=TRUE)
results4 <- targbetween_alldyads(my_network, multiple_sources,
  multiple_destinations, directed=FALSE, update=1000)
