Querying graph types

Description

This set of functions lets the user query different aspects of the graph itself. They are all concerned with wether the graph implements certain properties and will all return a logical scalar.

Usage

graph_is_simple()

graph_is_directed()

graph_is_bipartite()

graph_is_connected()

graph_is_tree()

graph_is_forest()

graph_is_dag()

graph_is_chordal()

graph_is_complete()

graph_is_isomorphic_to(graph, method = "auto", ...)

graph_is_subgraph_isomorphic_to(graph, method = "auto", ...)

Arguments

Value

A logical scalar

Functions

• graph_is_simple: Is the graph simple (no parallel edges)

• graph_is_directed: Is the graph directed

• graph_is_bipartite: Is the graph bipartite

• graph_is_connected: Is the graph connected

• graph_is_tree: Is the graph a tree

• graph_is_forest: Is the graph an ensemble of multiple trees

• graph_is_dag: Is the graph a directed acyclic graph

• graph_is_chordal: Is the graph chordal

• graph_is_complete: Is the graph fully connected

• graph_is_isomorphic_to: Is the graph isomorphic to another graph. See igraph::is_isomorphic_to()

• graph_is_subgraph_isomorphic_to: Is the graph an isomorphic subgraph to another graph. see igraph::is_subgraph_isomorphic_to()

Examples

gr <- create_tree(50, 4)

with_graph(gr, graph_is_tree())
