get_graph_actions(graph)
Arguments
graph |
A graph object of class |
Value
A df_tbl

Examples
# Create a random graph using the
# `add_gnm_graph()` function
graph <-
create_graph(
directed = FALSE) %>%
add_gnm_graph(
n = 10,
m = 15,
set_seed = 23)
# Add a graph action that sets a node
# attr column with a function; the
# main function `set_node_attr_w_fcn()`
# uses the `get_betweenness()` function
# to provide betweenness values in the
# `btwns` column
graph <-
graph %>%
add_graph_action(
fcn = "set_node_attr_w_fcn",
node_attr_fcn = "get_betweenness",
column_name = "btwns",
action_name = "get_btwns")
# To ensure that the action is
# available in the graph, use the
# `get_graph_actions()` function
graph %>% get_graph_actions()
