| add_n_node_clones {DiagrammeR} | R Documentation |
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)
graph |
a graph object of class
|
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 |
a graph object of class dgr_graph.
