Description

Using a dgr_graph object, render the graph in the RStudio Viewer.

Usage

render_graph(
  graph,
  layout = NULL,
  output = NULL,
  as_svg = FALSE,
  title = NULL,
  width = NULL,
  height = NULL
)

Arguments

graph

A graph object of class dgr_graph.

layout

A string specifying a layout type to use for node placement in this rendering. Possible layouts include: nicely, circle, tree, kk, and fr.

output

A string specifying the output type; graph (the default) renders the graph using the grViz() function and visNetwork renders the graph using the visnetwork() function.

as_svg

An option to render the graph as an SVG document.

title

An optional title for a graph when using output = "graph".

width

An optional parameter for specifying the width of the resulting graphic in pixels.

height

An optional parameter for specifying the height of the resulting graphic in pixels.

Examples

if (interactive()) {

  # Render a graph that's a
  # balanced tree
  create_graph() %>%
    add_balanced_tree(
      k = 2, h = 3
    ) %>%
    render_graph()

  # Use the `tree` layout for
  # better node placement in this
  # hierarchical graph
  create_graph() %>%
    add_balanced_tree(
      k = 2, h = 3
    ) %>%
    render_graph(layout = "tree")

  # Plot the same tree graph but
  # don't show the node ID values
  create_graph() %>%
    add_balanced_tree(
      k = 2, h = 3
    ) %>%
    set_node_attr_to_display() %>%
    render_graph(layout = "tree")

  # Create a circle graph
  create_graph() %>%
    add_gnm_graph(
      n = 55,
      m = 75,
      set_seed = 23
    ) %>%
    render_graph(
      layout = "circle"
    )

  # Render the graph using the
  # `visNetwork` output option
  create_graph() %>%
    add_balanced_tree(
      k = 2, h = 3
