create_random_graph: Create a randomized graph

Description

Create a graph of up to n nodes with randomized edge assignments.

Usage

create_random_graph(n, m, directed = FALSE, fully_connected = FALSE, display_labels = TRUE, set_seed = NULL, node_id = NULL)

Arguments

n

the number of nodes to use in the random graph.

m

the number of edges to use in the random graph.

directed

an option for whether the random graph should be undirected (default) or directed.

fully_connected

should the graph be fully connected (i.e. no free nodes).

display_labels

display node labels.

set_seed

supplying a value sets a random seed of the Mersenne-Twister implementation.

node_id

an optional vector of unique node ID values to apply to the randomized graph. The length of the vector should ideally correspond to the value supplied in n; vectors longer than the length of n will be truncated.

Examples

## Not run: 
# # Create a random, directed graph with 50 nodes and 75 edges
# random_graph_directed <-
#   create_random_graph(50, 75, directed = TRUE)
# 
# # Create a random, undirected graph that's fully connected
# random_graph_undirected <-
#   create_random_graph(30, 30, fully_connected = TRUE)
# 
# # Create a directed graph with a seed set so that it's reproducible
# directed_graph <-
#   create_random_graph(15, 34, set_seed = 50)
# 
# # Create a directed, random graph with a supplied set of node IDs
# random_directed_graph_letters <-
#   create_random_graph(n = 10, m = 20,
#                       directed = TRUE,
#                       node_id = LETTERS)
