Get the current selection of node IDs or edge IDs from a graph object of
class dgr_graph.
Examples
# Create a simple graph
graph <-
create_graph() %>%
add_path(n = 6)
# Select node `4`, then select
# all nodes a distance of 1 away
# from node `4`, and finally
# return the selection of nodes as
# a vector object
graph %>%
select_nodes(nodes = 4) %>%
select_nodes_in_neighborhood(
node = 4,
distance = 1) %>%
get_selection()
#> [1] 3 4 5
# Select edges associated with
# node `4` and return the
# selection of edges
graph %>%
select_edges_by_node_id(
nodes = 4) %>%
get_selection()
#> [1] 3 4
