Read and Robin J. Wilson. The atlas contains all undirected graphs with up to seven vertices, numbered from 0 up to 1252. The graphs are listed: </p> <ol> <li><p> in increasing order of number of nodes; </p> </li> <li><p> for a fixed number of nodes, in increasing order of the number of edges; </p> </li> <li><p> for fixed numbers of nodes and edges, in increasing order of the degree sequence, for example 111223 < 112222; </p> </li> <li><p> for fixed degree sequence, in increasing number of automorphisms. </p> </li></ol> <h3>Usage</h3> <pre> graph_from_atlas(n) atlas(...) </pre> <h3>Arguments</h3> <table summary="R argblock"> <tr valign="top"><td><code>n</code></td> <td> <p>The id of the graph to create.</p> </td></tr> <tr valign="top"><td><code>...</code></td> <td> <p>Passed to <code>graph_from_atlas</code>.</p> </td></tr> </table> <h3>Value</h3> <p>An igraph graph. </p> <h3>See Also</h3> <p>Other deterministic constructors: <code><a href="graph_from_edgelist.html">graph_from_edgelist</a>()</code>, <code><a href="graph_from_literal.html">graph_from_literal</a>()</code>, <code><a href="make_chordal_ring.html">make_chordal_ring</a>()</code>, <code><a href="make_empty_graph.html">make_empty_graph</a>()</code>, <code><a href="make_full_citation_graph.html">make_full_citation_graph</a>()</code>, <code><a href="make_full_graph.html">make_full_graph</a>()</code>, <code><a href="make_graph.html">make_graph</a>()</code>, <code><a href="make_lattice.html">make_lattice</a>()</code>, <code><a href="make_ring.html">make_ring</a>()</code>, <code><a href="make_star.html">make_star</a>()</code>, <code><a href="make_tree.html">make_tree</a>()</code> </p> <h3>Examples</h3> <pre> ## Some randomly picked graphs from the atlas graph_from_atlas(sample(0:1252, 1)) graph_from_atlas(sample(0:1252, 1)) </pre> <hr /><div style="text-align: center;">[Package <em>igraph</em> version 1.3.5 <a href="00Index.html">Index</a>]</div> </body></html>
