Get the closeness centrality values for all nodes in a graph.

get_closeness(graph, direction = "all")

Arguments

graph

a graph object of class dgr_graph.

direction

using all (the default), the search will ignore edge direction while traversing through the graph. With out, measurements of paths will be from a node whereas with in, measurements of paths will be to a node.

Value

a data frame with closeness values for each of the nodes.

Examples

# Create a random graph using the # `add_gnm_graph()` function graph <- create_graph() %>% add_gnm_graph( n = 10, m = 12, set_seed = 23) # Get closeness values for all nodes # in the graph graph %>% get_closeness()
#> id closeness #> 1 1 0.05263158 #> 2 2 0.06250000 #> 3 3 0.05555556 #> 4 4 0.06666667 #> 5 5 0.06666667 #> 6 6 0.04166667 #> 7 7 0.04347826 #> 8 8 0.05555556 #> 9 9 0.04166667 #> 10 10 0.04545455
# Add the closeness values to # the graph as a node attribute graph <- graph %>% join_node_attrs( df = get_closeness(.)) # Display the graph's node data frame graph %>% get_node_df()
#> id type label closeness #> 1 1 <NA> 1 0.05263158 #> 2 2 <NA> 2 0.06250000 #> 3 3 <NA> 3 0.05555556 #> 4 4 <NA> 4 0.06666667 #> 5 5 <NA> 5 0.06666667 #> 6 6 <NA> 6 0.04166667 #> 7 7 <NA> 7 0.04347826 #> 8 8 <NA> 8 0.05555556 #> 9 9 <NA> 9 0.04166667 #> 10 10 <NA> 10 0.04545455
