| connectedComp {RBGL} | R Documentation |
The connected components in an undirected graph are identified. If the graph is directed then the weakly connected components are identified.
connectedComp(g)
g |
graph with edgemode “undirected” |
Uses a depth first search approach to identifying all the connected
components of an undirected graph. If the input, g, is a directed
graph it is first transformed to an undirected graph (using
ugraph).
A list of length equal to the number of connected components in
g. Each element of the list contains a vector of the node
labels for the nodes that are connected.
