假设我有一个不同长度的矢量列表,例如:
listToMatrix <- list(c(1,2,3,4),c(2,15,6),c(9,1,4,6,2,5))
问题是如何将此列表放入矩阵中(可以将空格保留为零),因为我想稍后对计算进行矢量化。
答案 0 :(得分:0)
我们可以使用Session.OpenRequest openRequest = new Session.OpenRequest(Login.this);
openRequest.setPermissions(Arrays.asList("email", "user_birthday"));
openRequest.setCallback(new Session.StatusCallback() {
// callback when session changes state
@Override
public void call(Session session, SessionState state,
Exception exception) {
if (session.isOpened()) {
// make request to the /me API
Request request = Request.newMeRequest(session,
new Request.GraphUserCallback() {
// callback after Graph API response with user
// object
@Override
public void onCompleted(GraphUser gUser,
Response response) {
if (gUser != null) {
String email = gUser.getProperty("email").toString();
String firstName = gUser.getFirstName();
String lastName = gUser.getLastName();
String username = gUser.getUsername();
String birthday = gUser.getBirthday();
}
}
});
request.executeAsync();
}
}
}
);
中的stri_list2matrix
。我们将输出转换为library(stringi)
并将尺寸更改为输出矩阵(&#39; m1&#39;)。
