Get the coreness values for all nodes in a graph.

get_coreness(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 coreness values 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 coreness values for # all nodes in the graph graph %>% get_coreness()
#> id coreness #> 1 1 3 #> 2 2 3 #> 3 3 2 #> 4 4 3 #> 5 5 3 #> 6 6 3 #> 7 7 3 #> 8 8 2 #> 9 9 2 #> 10 10 0
# Add the coreness values # to the graph as a node # attribute graph <- graph %>% join_node_attrs( df = get_coreness(.)) # Display the graph's node data frame graph %>% get_node_df()
#> id type label coreness #> 1 1 <NA> 1 3 #> 2 2 <NA> 2 3 #> 3 3 <NA> 3 2 #> 4 4 <NA> 4 3 #> 5 5 <NA> 5 3 #> 6 6 <NA> 6 3 #> 7 7 <NA> 7 3 #> 8 8 <NA> 8 2 #> 9 9 <NA> 9 2 #> 10 10 <NA> 10 0
