select_last_nodes_created(graph)

Arguments

graph

a graph object of class dgr_graph.

Value

a graph object of class dgr_graph.

Examples

# Create a graph and add 4 nodes # in 2 separate function calls graph <- create_graph() %>% add_n_nodes( n = 2, type = "a", label = c("a_1", "a_2")) %>% add_n_nodes( n = 2, type = "b", label = c("b_1", "b_2")) # Select the last nodes created (2 nodes # from the last function call) and then # set their color to be `red` graph <- graph %>% select_last_nodes_created() %>% set_node_attrs_ws( node_attr = color, value = "red") %>% clear_selection() # Display the graph's internal node # data frame to verify the change graph %>% get_node_df()
#> id type label color #> 1 1 a a_1 <NA> #> 2 2 a a_2 <NA> #> 3 3 b b_1 red #> 4 4 b b_2 red
