Extract node names.

Source: R/nodes.R

Extract node names.

node_get_names(.net)

node_name_attr(.net)

Arguments

.net

network of class igraph or network.

Value

  • node_get_names()

    • character vector

  • node_name_attr():

    • character scalar

Details

  • node_get_names()

    • Uses node_name_attr() to determine node names.

  • node_name_attr()

    • If .net is an igraph object, node_get_names() returns the node (vertex) attribute "name".

      • If "name" is not a node attribute, node_get_names() returns node_seq(.net).

    • If .net is a network object, node_get_names() returns the node (vertex) attribute "vertex.names".

Examples

node_get_names(.net = florence_business_ig)
