node_topology | R Documentation |
These functions calculate properties that are dependent on the overall topology of the graph.
node_dominator(root, mode = "out")
node_topo_order(mode = "out")
root |
The node to start the dominator search from |
mode |
How should edges be followed. Either |
A vector of the same length as the number of nodes in the graph
node_dominator()
: Get the immediate dominator of each node. Wraps igraph::dominator_tree()
.
node_topo_order()
: Get the topological order of nodes in a DAG. Wraps igraph::topo_sort()
.
# Sort a graph based on its topological order
create_tree(10, 2) %>%
arrange(sample(graph_order())) %>%
mutate(old_ind = seq_len(graph_order())) %>%
arrange(node_topo_order())
