Description

Delete one or more graph actions stored within a graph object of class dgr_graph).

Usage

delete_graph_actions(graph, actions)

Value

A graph object of class dgr_graph.

Arguments

graph

A graph object of class dgr_graph.

actions

Either a vector of integer numbers indicating which actions to delete (based on action_index values), or, a character vector corresponding to action_name values.

Examples

# Create a random graph using the
# `add_gnm_graph()` function
graph <-
  create_graph() %>%
  add_gnm_graph(
    n = 5,
    m = 8,
    set_seed = 23)

# Add three graph actions to the
# graph
graph <-
  graph %>%
  add_graph_action(
    fcn = "set_node_attr_w_fcn",
    node_attr_fcn = "get_pagerank",
    column_name = "pagerank",
    action_name = "get_pagerank") %>%
  add_graph_action(
    fcn = "rescale_node_attrs",
    node_attr_from = "pagerank",
    node_attr_to = "width",
    action_name = "pagerank_to_width") %>%
  add_graph_action(
    fcn = "colorize_node_attrs",
    node_attr_from = "width",
    node_attr_to = "fillcolor",
    action_name = "pagerank_fillcolor")

# View the graph actions for the graph
# object by using the `get_graph_actions()`
# function
graph %>% get_graph_actions()

# Delete the second and third graph
# actions using `delete_graph_actions()`
graph <-
  graph %>%
  delete_graph_actions(
    actions = c(2, 3))

# Verify that these last two graph
# actions were deleted by again using
# the `get_graph_actions()` function
graph %>% get_graph_actions()
