我有一个缩放的数据框(在上面应用了scale()之后)。

这是数据帧的示例和str()。

df <- structure(list(user_id = c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L,

我已经在上面的df中显示了前10列和100行。

现在,如果我想按时间戳排列(其他专栏让我可以毫无问题地进行此操作):

df %>% dplyr::arrange(timestamp)

我得到:

  

arrange_impl(.data,点)中的错误:参数1是不受支持的类型   矩阵

但是,如果我将其转移到data.table,它将可以正常工作:

df %>% as.data.table() %>% dplyr::arrange(timestamp)

如果我在未缩放的df上运行它,则可以正常运行,但如果执行以下操作:

df_unscaled %>%
  mutate_at(vars(-"user_id", -"obs_id",
                 -"scroll_id", -"row_num",
                 -"scroll_length"),
            scale) %>% arrange(timestamp)

我遇到同样的错误:

  

arrange_impl(.data,点)中的错误:参数1是不受支持的类型   矩阵

请告知这里有什么问题?是打破dplyr::arrange()

的类型吗

如果您需要我可以共享的示例数据,请告诉我在何处共享它。
