WeaklyConnectedGraphComponents

WeaklyConnectedGraphComponents[g] gives the weakly connected components of the graph g.

WeaklyConnectedGraphComponents[g,{v1,v2,…}] gives the weakly connected components that include at least one of the vertices v1, v2, … .

WeaklyConnectedGraphComponents[g,patt] gives the connected components that include a vertex that matches the pattern patt.

WeaklyConnectedGraphComponents[{v->w,…},…] uses rules v->w to specify the graph g.
