In DiagrammeR: Graph/Network Visualization

Copy an edge attribute column and set the name

Description

Within a graph's internal edge data frame (edf), copy the contents an existing edge attribute and create a distinct edge attribute within the edf with a different attribute name.

Usage

copy_edge_attrs(graph, edge_attr_from, edge_attr_to)

Arguments

graph	A graph object of class dgr_graph.
edge_attr_from	The name of the edge attribute column from which values will be copied.
edge_attr_to	The name of the new edge attribute column to which the copied values will be placed.

Value

A graph object of class dgr_graph.

Examples

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

# Get the graph's internal
# edf to show which edge
# attributes are available
graph %>% get_edge_df()

# Make a copy the `color`
# edge attribute as the
# `color_2` edge attribute
graph <-
  graph %>%
  copy_edge_attrs(
    edge_attr_from = color,
    edge_attr_to = color_2)

# Get the graph's internal
# edf to show that the edge
# attribute had been copied
graph %>% get_edge_df()
