Extracting the giant connected component from an igraph object
The function uses igraph::clusters and igraph::induced.subgraph to extract the giant component of an igraph object.
An igraph object.
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.
getgcc returns an igraph object with the giant connected
component of an igraph object.
