definition of connectedness to use; must be one of "strong", "weak", "unilateral", or "recursive".

comp.dist.precomp

a component.dist object precomputed for the graph to be analyzed (optional).

Value

TRUE iff g is connected, otherwise FALSE

Details

is.connected determines whether the elements of g are connected under the definition specified in connected. (See component.dist for details.) Since is.connected is really just a wrapper for component.dist, an object created with the latter can be supplied (via comp.dist.precomp) to speed computation.
