Add n new nodes to a graph object of class dgr_graph which are clones of a node already in the graph. All node attributes are preserved except for the node label attribute (to maintain the uniqueness of non-NA node label values). A vector of node label can be provided to bind new labels to the cloned nodes.

add_n_node_clones(graph, n, node, label = NULL)

Arguments

graph

a graph object of class dgr_graph.

n

the number of node clones to add to the graph.

node

a node ID corresponding to the graph node to be cloned.

label

an optional vector of node label values. The vector length should correspond to the value set for n.

Value

a graph object of class dgr_graph.

Examples

# Create a graph with a path of # nodes; supply `label`, `type`, # and `value` node attributes graph <- create_graph() %>% add_path( n = 3, label = c("d", "g", "r"), type = c("a", "b", "c")) # Display the graph's internal # node data frame graph %>% get_node_df()
#> id type label #> 1 1 a d #> 2 2 b g #> 3 3 c r
# Create 3 clones of node `1` # but assign new node label # values (leaving `label` as # NULL yields NA values) graph <- graph %>% add_n_node_clones( n = 3, node = 1, label = c("x", "y", "z")) # Display the graph's internal # node data frame: nodes `4`, # `5`, and `6` are clones of `1` graph %>% get_node_df()
#> id type label #> 1 1 a d #> 2 2 b g #> 3 3 c r #> 4 4 a x #> 5 5 a y #> 6 6 a z
