graph.graphdb: Load a graph from the graph database for testing graph...

In igraph: Network Analysis and Visualization

Load a graph from the graph database for testing graph isomorphism.

Description

graph.graphdb() was renamed to graph_from_graphdb() to create a more consistent API.

Usage

graph.graphdb(
  url = NULL,
  prefix = "iso",
  type = "r001",
  nodes = NULL,
  pair = "A",
  which = 0,
  base = "http://cneurocvs.rmki.kfki.hu/graphdb/gzip",
  compressed = TRUE,
  directed = TRUE
)

Arguments

url	If not NULL it is a complete URL with the file to import.
prefix	Gives the prefix. See details below. Possible values: iso, i2, si4, si6, mcs10, mcs30, mcs50, mcs70, mcs90.
type	Gives the graph type identifier. See details below. Possible values: r001, r005, r01, r02, m2D, m2Dr2, m2Dr4, m2Dr6 m3D, m3Dr2, m3Dr4, m3Dr6, m4D, m4Dr2, m4Dr4, m4Dr6, b03, b03m, b06, b06m, b09, b09m.
nodes	The number of vertices in the graph.
pair	Specifies which graph of the pair to read. Possible values: A and B.
which	Gives the number of the graph to read. For every graph type there are a number of actual graphs in the database. This argument specifies which one to read.
base	The base address of the database. See details below.
compressed	Logical constant, if TRUE than the file is expected to be compressed by gzip. If url is NULL then a ‘.gz’ suffix is added to the filename.
directed	Logical constant, whether to create a directed graph.
