create_node_df: Create a node data frame

Description

Combine several vectors for nodes and their attributes into a data frame, which can be combined with other similarly-generated data frames, or, added to a graph object. A node data frame, or ndf, has at least the following columns:

Usage

create_node_df(n, type = NULL, label = NULL, ...)

Value

A node data frame (ndf).

Arguments

n: The total number of nodes to include in the node data frame.
type: An optional type for each node.
label: An optional label for each node.
...: One or more vectors for associated node attributes.

Details

id (of type integer)
type (of type character)
label (of type character)

An arbitrary number of additional columns containing aesthetic or data attributes can be part of the ndf, so long as they follow the aforementioned columns.

Examples

Run this code

# Create a node data frame (ndf) where the labels
# are equivalent to the node ID values (this is not
# recommended); the `label` and `type` node
# attributes will always be a `character` class
# whereas `id` will always be an `integer`
node_df <-
  create_node_df(
    n = 4,
    type = c("a", "a", "b", "b"),
    label = TRUE)

# Display the node data frame
node_df

# Create an ndf with distinct labels and
# additional node attributes (where their classes
# will be inferred from the input vectors)
node_df <-
  create_node_df(
    n = 4,
    type = "a",
    label = c(2384, 3942, 8362, 2194),
    style = "filled",
    color = "aqua",
    shape = c("circle", "circle",
              "rectangle", "rectangle"),
    value = c(3.5, 2.6, 9.4, 2.7))
