get_cmty_walktrap: Get community membership using the Walktrap method

In rich-iannone/DiagrammeR: Graph/Network Visualization

Get community membership using the Walktrap method

Description

With the Walktrap community finding algorithm, obtain the group membership values for each of the nodes in the graph.

Usage

get_cmty_walktrap(graph, steps = 4)

Arguments

graph	A graph object of class dgr_graph.
steps	the number of steps to take for each of the random walks.

Value

A data frame with group membership assignments for each of the nodes.

Examples

# Create a random graph using the
# `add_gnm_graph()` function
graph <-
  create_graph(
    directed = FALSE) %>%
  add_gnm_graph(
    n = 10,
    m = 15,
    set_seed = 23)

# Get the group membership
# values for all nodes in the
# graph through the Walktrap
# community finding algorithm
graph %>%
  get_cmty_walktrap()

# Add the group membership
# values to the graph as a
# node attribute
graph <-
  graph %>%
  join_node_attrs(
    df = get_cmty_walktrap(.))

# Display the graph's
# node data frame
graph %>% get_node_df()
