Description

Obtain a data frame with detailed information on nodes and their interrelationships within a graph.

Usage

node_info(graph)

Arguments

graph

a graph object of class dgr_graph.

Value

a data frame containing information specific to each node within the graph.

Examples

# NOT RUN {
# Set a seed
set.seed(23)

# Create a node data frame (ndf)
ndf <-
  create_node_df(
    n = 26,
    label = TRUE,
    type = c(rep("a", 7),
             rep("b", 9),
             rep("c", 8),
             rep("d", 2)))

# Create an edge data frame (edf)
edf <-
  create_edge_df(
    from = sample(1:26, replace = TRUE),
    to = sample(1:26, replace = TRUE),
    rel = c(rep("rel_a", 7),
            rep("rel_b", 9),
            rep("rel_c", 8),
            rep("rel_d", 2)))

# Create a graph using the ndf and edf
graph <-
  create_graph(
    nodes_df = ndf,
    edges_df = edf)
