create_node_df | R Documentation |
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:
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, see node_aes()
for additional attributes that can be used with ..., so long as they follow the aforementioned
columns.
create_node_df(n, type = NULL, label = NULL, ...)

# Create a node data frame (ndf) where the labels
