| components {sna} | R Documentation |
Returns the number of components within dat, using the connectedness rule given in connected.
components(dat, connected="strong", comp.dist.precomp=NULL)
dat |
An nxn adjacency matrix |
connected |
The symmetrizing rule to be used by symmetrize before components are extracted |
comp.dist.precomp |
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 weak components can be returned if so desired. For symmetric matrices, this is obviously a moot point.
