Gateway Coefficient

Description

Computes the gateway coefficient for each node. The gateway coefficient measures a node's connections between its community and other communities. Nodes that are solely responsible for inter-community connectivity will have higher gateway coefficient values. Positive and negative signed weights for gateway coefficients are computed separately.

Usage

gateway(
  A,
  comm = c("walktrap", "louvain"),
  cent = c("strength", "betweenness")
)

Arguments

`A`	Network adjacency matrix
`comm`	A vector of corresponding to each item's community. Defaults to `"walktrap"` for the `cluster_walktrap` community detection algorithm. Set to `"louvain"` for the `louvain` community detection algorithm. Can also be set to user-specified communities (see examples)
`cent`	Centrality to community gateway coefficient. Defaults to `"strength"`. Set to `"betweenness"` to use the `betweenness` centrality

Value

Returns a list containing:

`overall`	Gateway coefficient without signs considered
`positive`	Gateway coefficient with only positive sign
`negative`	Gateway coefficient with only negative sign
