Add a new node to network

Add a node to the network. Takes the node id (string), the node type (string), and the node level (int).

add_node(sbm, id, type = NULL, show_messages = TRUE)

Arguments

sbm	sbm_network object as created by new_sbm_network.
id	Unique identifying name for node.
type	Type of node (string). This is used to distinguish multipartite networks. E.g. "person", or "publication", etc..
show_messages	Should function inform of its actions such as when a model already exists so no changes are made?

Value

An S3 object of class sbm_network. For details see new_sbm_network section "Class structure."

Examples

# Start with network with 5 nodes.
net <- sim_random_network(n_nodes = 5, prob_of_edge = 1, setup_model = TRUE)

# Verify nodes
net$nodes

#>   id     block type 
#>   <chr>  <chr> <chr>
#> 1 node_1 node  node 
#> 2 node_2 node  node 
#> 3 node_3 node  node 
#> 4 node_4 node  node 
#> 5 node_5 node  node 
net %>% state()

# Add two nodes
net <- net %>%
  add_node('new_node1', type = 'node') %>%
  add_node('new_node2', type = 'node')

# New nodes are added to node data and state
