This means that it is not possible to use igraph objects that were created (and possibly saved to a file) with an older igraph version. </p> <h3>Usage</h3> <pre> graph_version(graph) </pre> <h3>Arguments</h3> <table summary="R argblock"> <tr valign="top"><td><code>graph</code></td> <td> <p>The input graph. If it is missing, then the version number of the current data format is returned.</p> </td></tr> </table> <h3>Details</h3> <p><code>graph_version</code> queries the current data format, or the data format of a possibly older igraph graph. </p> <p><code><a href="upgrade_graph.html">upgrade_graph</a></code> can convert an older data format to the current one. </p> <h3>Value</h3> <p>A character scalar. </p> <h3>See Also</h3> <p>upgrade_graph to convert the data format of a graph. </p> <hr /><div style="text-align: center;">[Package <em>igraph</em> version 1.3.5 <a href="00Index.html">Index</a>]</div> </body></html>
