Returns the number of components within dat, using the connectedness rule given in connected.
components(dat, connected="strong", comp.dist.precomp=NULL)A vector containing the number of components for each graph in dat
one or more input graphs.
the the component definition to be used by component.dist during component extraction.
a component size distribution object from component.dist (optional).

The connected parameter corresponds to the rule parameter of component.dist. By default, components returns the number of strong components, but other component types can be returned if so desired. (See component.dist for details.) For symmetric matrices, this is obviously a moot point.
