Fluid Communities Detection — community

Simulates fluid dynamics where communities compete for nodes. Requires specifying the number of communities.

Usage

community_fluid(x, no.of.communities, ...)

com_fl(x, no.of.communities, ...)

Arguments

x: Network input
no.of.communities: Number of communities to detect. Required.
...: Additional arguments passed to to_igraph

Value

A cograph_communities object

A cograph_communities object. See detect_communities.

Examples

if (requireNamespace("igraph", quietly = TRUE)) {
  g <- igraph::make_graph("Zachary")

  # Detect exactly 2 communities
  comm <- community_fluid(g, no.of.communities = 2)
}
m <- matrix(runif(25), 5, 5); diag(m) <- 0
net <- as_cograph(m)
com_fl(net, no.of.communities = 2)
