In cograph: Analysis and Visualization of Complex Networks

Neighborhood Overlap (Jaccard) for Each Edge

Description

Convenience wrapper around edge_centrality that returns only the overlap measure sorted by overlap descending.

Usage

neighborhood_overlap(x, top = NULL, directed = NULL, digits = NULL, ...)

Arguments

x	Network input: matrix, igraph, network, cograph_network, or tna object.
top	Integer or NULL. Return only the top N edges. Default NULL.
directed	Logical or NULL. Default NULL (auto-detect).
digits	Integer or NULL. Round numeric columns. Default NULL.
...	Additional arguments passed to edge_centrality.

Value

A data frame sorted by overlap (descending) with columns: from, to, weight (if weighted), overlap, shared_neighbors.

Examples

adj <- matrix(c(0, 1, 1, 1, 0, 1, 1, 1, 0), 3, 3)
rownames(adj) <- colnames(adj) <- c("A", "B", "C")
cograph::neighborhood_overlap(adj)
