##### Querying node types

These functions all lets the user query whether each node is of a certain type. All of the functions returns a logical vector indicating whether the node is of the type in question. Do note that the types are not mutually exclusive and that nodes can thus be of multiple types.

##### Usage
node_is_cut()node_is_root()node_is_leaf()node_is_sink()node_is_source()node_is_isolated()node_is_universal(mode = "out")node_is_simplical(mode = "out")node_is_center(mode = "out")node_is_adjacent(to, mode = "all", include_to = TRUE)node_is_keyplayer(k, p = 0, tol = 1e-04, maxsec = 120,
roundsec = 30)
##### Arguments
mode

The way edges should be followed in the case of directed graphs.

to

The nodes to test for adjacency to

include_to

Should the nodes in to be marked as adjacent as well

k

The number of keyplayers to identify

p

The probability to accept a lesser state

tol

Optimisation tolerance, below which the optimisation will stop

maxsec

The total computation budget for the optimization, in seconds

roundsec

Number of seconds in between synchronizing workers' answer

##### Value

A logical vector of the same length as the number of nodes in the graph.

##### Functions

• node_is_cut: is the node a cut node (articaultion node)

• node_is_root: is the node a root in a tree

• node_is_leaf: is the node a leaf in a tree

• node_is_sink: does the node only have incomming edges

• node_is_source: does the node only have outgoing edges

• node_is_isolated: is the node unconnected

• node_is_universal: is the node connected to all other nodes in the graph

• node_is_simplical: are all the neighbors of the node connected

• node_is_center: does the node have the minimal eccentricity in the graph

• node_is_adjacent: is a node adjacent to any of the nodes given in to

• node_is_keyplayer: Is a node part of the keyplayers in the graph (influenceR)
