rgraph6: Representing Graphs as 'graph6', 'digraph6' or 'sparse6' Strings

Description

logo

Encode network data as strings of printable ASCII characters. Implemented functions include encoding and decoding adjacency matrices, edgelists, igraph, and network objects to/from formats 'graph6', 'sparse6', and 'digraph6'. The formats and methods are described in McKay, B.D. and Piperno, A (2014) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1016/j.jsc.2013.09.003")}.

Details

Formats 'graph6', 'sparse6' and 'digraph6' represent graphs as strings of printable ASCII characters. The formats are due to Brendan McKay who implemented them in his program Nauty (McKay 1978, 1980, 2003, McKay & Piperno 2014), and are described in detail here. Package rgraph6 is a native R implementation of these formats.

The main functions are as_graph6(), as_digraph6(), as_sparse6() for encoding network data and igraph_from_text() and network_from_text() for decoding. There are also other low-level functions to decode directly from digraph6, graph6, and sparse6.
