getgcc: Extracting the giant connected component from an igraph...

In bc3net: Gene Regulatory Network Inference with Bc3net

Description

The function uses igraph::clusters and igraph::induced.subgraph to extract the giant component of an igraph object.

Usage

  getgcc(net)

Arguments

net	An igraph object.

Details

In a connected component of an undirected graph all pairs of vertices u and v are reachable by a path. The giant connected component describes the largest connected component of a graph object.

Value

getgcc returns an igraph object with the giant connected component of an igraph object.
