Create a node data frame
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:
create_node_df(n, type = NULL, label = NULL, ...)
n |
The total number of nodes to include in the node data frame. |
type |
An optional |
label |
An optional |
... |
One or more vectors for associated node attributes. |
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.

# 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`
