Generate Simple Node2Vec Test Data

node2vec_test_data.Rd

Creates graphs with known structure to verify node2vec is working correctly. The following options exists:

  • "barbell" - Two dense clusters connected by single edge.

  • "cavemen" - Multiple isolated cliques with sparse inter-connections.

  • "stochastic_block" - Communities with controlled edge probabilities.

Usage

node2vec_test_data(
  test_type = c("barbell", "cavemen", "stochastic_block"),
  n_nodes_per_cluster = 10L,
  n_clusters = 3L,
  p_within = 0.8,
  p_between = 0.05,
  seed = 42L
)

Arguments

test_type

String. One of c("barbell", "cavemen", "stochastic_block")

n_nodes_per_cluster

Integer. Nodes per cluster/community.

n_clusters

Integer. Number of clusters.

p_within

Numeric. Probability of edges within cluster (0-1).

p_between

Numeric. Probability of edges between clusters (0-1).

seed

Integer. Random seed.

Value

A list containing:

edges

data.table with from, to, edge_type

node_labels

data.table with node, cluster
