我有一个图g，其中顶点有一个属性＆＃39; group＆＃39;。我想根据group属性测量图形的模块性。以下是我的处理方式：
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.2.3/jquery.min.js"></script>
<a id="lap1" class="button" href="#">Lap 1</a>
<a id="lap2" class="button" href="#">Lap 2</a>
<a id="lap3" class="button" href="#">Lap 3</a>
</br>
<iframe id="video" width="420" height="315" src="//www.youtube.com/embed/J4LI_EqnJq8?autoplay=1" frameborder="0" allowfullscreen></iframe>
群集对象cl如下所示：
cl = Clustering(g.vs()['group'])
modul = g2.modularity(cl,weights=None)
为什么iGraph会引发此错误：

我错过了什么吗？
答案 0 :(得分：2)
function my_project_updated_send_email( $post_id ) {
// If this is just a revision, don't send the email.
if ( wp_is_post_revision( $post_id ) )
return;
if ( post_password_required($post_id) ) {
$post_title = get_the_title( $post_id );
$post_url = get_permalink( $post_id );
$subject = 'New Report Published by MySelf';
$email_to=$_POST["email_to"];
$email_to = preg_replace('/\s+/', '', $email_to);
$password = $_POST["post_password"];
$password = preg_replace('/\s+/', '', $password);
$message = "Here is the link for you on our website:\n\n";
$message .= $post_title . ": " . $post_url . "\n\n";
$message .= "Your Password is :" .$password;
$headers = "From: ime@my.com";
// Send email to admin.
if( ($password!=="") || ($email_to!=="") ){
wp_mail($email_to, $subject, $message, $headers );
}
}
}
add_action( 'save_post', 'my_project_updated_send_email' );
函数需要一个迭代，它产生整数作为第一个参数，而不是modularity个对象。顺便提一下，Clustering完全符合您的要求，因此无需创建g.vs["group"]：
Clustering如果你真的想要一个g.modularity(g.vs["group"])
对象，你需要构建一个Clustering，然后使用它的VertexClustering 属性（它将依次调用{ {1}}图表方法）：
modularity
