Examples


# Small edge list to build network
edges <- dplyr::tribble(
  ~from, ~to,
  "a1"   , "b1"   ,
  "a1"   , "b2"   ,
  "a1"   , "b3"   ,
  "a2"   , "b1"   ,
  "a2"   , "b4"   ,
  "a3"   , "b1"
)

# A small simulated network with no blocks
net <- new_sbm_network(edges)

n_blocks(net)
#> [1] 0

# Add some two random blocks
net %>% initialize_blocks(2) %>% n_blocks()
#> [1] 2

# Add a block per node
net %>% initialize_blocks() %>% n_blocks()
#> [1] 2
