select_nodes_by_id {DiagrammeR}R Documentation

Select nodes in a graph by ID values

Description

Select nodes in a graph object of class dgr_graph by their node ID values. If nodes have IDs that are monotonically increasing integer values, then numeric ranges can be used for the selection.

Usage

select_nodes_by_id(graph, nodes, set_op = "union")

Arguments

graph

a graph object of class dgr_graph that is created using create_graph.

nodes

a vector of node IDs for the selection of nodes present in the graph.

set_op

the set operation to perform upon consecutive selections of graph nodes. This can either be as a union (the default), as an intersection, or, as a difference on the previous selection, if it exists.

Value

a graph object of class dgr_graph.
