add_grid_3d: Add a 3D grid of nodes to the graph

In DiagrammeR: Graph/Network Visualization

Add a 3D grid of nodes to the graph

Description

With a graph object of class dgr_graph, add a three-dimensional grid to the graph.

Usage

add_grid_3d(
  graph,
  x,
  y,
  z,
  type = NULL,
  label = TRUE,
  rel = NULL,
  node_aes = NULL,
  edge_aes = NULL,
  node_data = NULL,
  edge_data = NULL
)

Arguments

graph	A graph object of class dgr_graph.
x	The number of nodes in the x direction.
y	The number of nodes in the y direction.
z	The number of nodes in the z direction.
type	An optional string that describes the entity type for the nodes to be added.
label	Either a vector object of length x * y * z that provides optional labels for the new nodes, or, a logical value where setting to TRUE ascribes node IDs to the label and FALSE yields a blank label.
rel	An optional string for providing a relationship label to all new edges created in the grid.
node_aes	An optional list of named vectors comprising node aesthetic attributes. The helper function node_aes() is strongly recommended for use here as it contains arguments for each of the accepted node aesthetic attributes (e.g., shape, style, color, fillcolor).
edge_aes	An optional list of named vectors comprising edge aesthetic attributes. The helper function edge_aes() is strongly recommended for use here as it contains arguments for each of the accepted edge aesthetic attributes (e.g., shape, style, penwidth, color).
node_data	An optional list of named vectors comprising node data attributes. The helper function node_data() is strongly recommended for use here as it helps bind data specifically to the created nodes.
edge_data	An optional list of named vectors comprising edge data attributes. The helper function edge_data() is strongly recommended for use here as it helps bind data specifically to the created edges.

Value

A graph object of class dgr_graph.

Examples

# Create a new graph and add
# a 2 x 2 x 2 grid
graph <-
  create_graph() %>%
  add_grid_3d(
    x = 2, y = 2, z = 2,
    type = "grid")

# Get node information
# from this graph
graph %>%
  get_node_info()

# Attributes can be specified
# in extra arguments and these
# are applied in order; Usually
# these attributes are applied
# to nodes (e.g., `type` is a
# node attribute) but the `rel`
# attribute will apply to the
# edges
graph_w_attrs <-
  create_graph() %>%
  add_grid_3d(
    x = 2, y = 2, z = 2,
    label = c(
      "one", "two", "three",
      "four", "five", "six",
      "seven", "eight"),
    type = c(
      "a", "a", "b",
      "b", "c", "c",
      "d", "d"),
    rel = "grid",
    node_data = node_data(
      value = c(
        1.2, 8.4, 3.4,
        5.2, 6.1, 2.6,
        6.3, 9.3)))

# Get the graph's node data frame
graph_w_attrs %>% get_node_df()

# Get the graph's edge data frame
graph_w_attrs %>% get_edge_df()
