get_dice_similarity: Get Dice similarity coefficient scores

Description

Get the Dice similarity coefficient scores for one or more nodes in a graph.

Usage

get_dice_similarity(graph, nodes = NULL, direction = "all", round_to = 3)

Arguments

graph

a graph object of class dgr_graph.

nodes

an optional vector of node IDs to consider for Dice similarity scores. If not supplied, then similarity scores will be provided for every pair of nodes in the graph.

direction

using all (the default), the function will ignore edge direction when determining scores for neighboring nodes. With out and in, edge direction for neighboring nodes will be considered.

round_to

the maximum number of decimal places to retain for the Dice similarity coefficient scores. The default value is 3.

Value

a matrix with Dice similarity values for each pair of nodes considered.

Examples

# NOT RUN {
# Create a random graph
graph <-
  create_random_graph(
    n = 10, m = 22,
    set_seed = 23)

# Get the Dice similarity values for
# nodes `5`, `6`, and `7`
get_dice_similarity(graph, nodes = 5:7)
#>       5     6     7
#> 5 1.000 0.500 0.444
#> 6 0.500 1.000 0.545
#> 7 0.444 0.545 1.000
# }
