如何旋转R中带有节和子节的列组成的数据框

12

我有一个下面提到的数据框：

structure(
  list(ID = c("P-1", " P-1", "P-1", "P-2", "P-3", "P-4", "P-5", "P-6", "P-7",
              "P-8"),
       Date = c("2020-03-16 12:11:33", "2020-03-16 13:16:04",
                "2020-03-16 06:13:55", "2020-03-16 10:03:43",
                "2020-03-16 12:37:09", "2020-03-16 06:40:24",
                "2020-03-16 09:46:45", "2020-03-16 12:07:44",
                "2020-03-16 14:09:51", "2020-03-16 09:19:23"),
       Status = c("SA", "SA", "SA", "RE", "RE", "RE", "RE", "XA", "XA", "XA"),
       Flag = c("L", "L", "L", NA, "K", "J", NA, NA, "H", "G"),
       Value = c(5929.81, 5929.81, 5929.81, NA, 6969.33, 740.08, NA, NA, 1524.8,
                 NA),
       Flag2 = c("CL", "CL", "CL", NA, "RY", "", NA, NA, "", NA),
       Flag3 = c(NA, NA, NA, NA, "RI", "PO", NA, "SS", "DDP", NA)),
  .Names=c("ID", "Date", "Status", "Flag", "Value", "Flag2", "Flag3"),
  row.names=c(NA, 10L), class="data.frame")

我正在使用以下代码：

    df %>% mutate(L = ifelse(Flag == "L",1,0),
                  K = ifelse(Flag == "K",1,0),
                  # etc for Flag) %>%
      mutate(sub_status = NA) %>%
      mutate(sub_status = ifelse(!is.na(Flag2) & Flag3 == 0, "a", sub_status),
             sub_status = ifelse(is.na(Flag2) & Flag3 != 0, "b", sub_status),
             # etc for sub-status) %>%
      mutate(value_class = ifelse(0 <= Value & Value <= 15000, "0-15000",
                                  "15000-50000")) %>%
      group_by(Date, status, sub_status, value_class) %>%
      summarise(L = sum(L),
                K = sum(K),
                # etc
                count = n())

为我提供以下输出：

    Date         Status  sub_status   value_class G H I J K L NA Count
    2020-03-20   SA      a            0-15000     0 0 0 0 1 1 0  2
    2020-03-20   SA      b            0-15000     0 0 0 0 1 0 0  1
    ................
    ................

我想使用来获得以下输出DF，其中该Status列具有不同的3个值，并且Flag2具有value或[null]或NA，最后该Flag3列具有不同的7个值，具有[null]或NA。对于一个不同ID的Flag3列，我们有多个列。

我需要通过创建一个基于Value0-15000、15000-50000 的3组来创建以下数据框。

  • 如果对于唯一ID，Flag2其值不是0或[null] / NA，但Flag3值是0或[null] / NA，则它将是a。
  • 如果对于唯一ID，Flag3其值不是0或[null] / NA，但Flag2值是0或[null] / NA，则它将是b
  • 如果对于唯一ID，两个Flag2＆Flag3都具有非0或[Null] / NA的值，则它将为c
  • 如果对于唯一的ID两者，Flag2＆Flag3都为0或[Null] / NA，则为d

我想将上述datafrmae安排在带有percentand Total列的以下结构中。

我已经提到过2/5要显示的百分比，即状态将除以总计，而状态将sub_status除以其各自的百分比Status。

16/03/2020         0 - 15000                    15000 - 50000

我已经提到了基于最新日期为16/03/2020的必需输出，如果该数据框没有最新日期，则将startdate所有值0保留在输出数据框中。百分比列仅供参考，将计算出百分比值。

另外，我想保持结构静态。例如，如果一天中不存在任何参数，则输出结构将与0值相同。

例如，假设date 17/03/2020没有任何带有status SA或sub_status c的行，则占位符将出现在输出中，值为0。

@akrun：我保留的百分比列2/5仅用于表示目的。只有百分比值，带小数点的2个小数点带有百分比符号。
— user9211845
@akrun：请建议是否可以通过R :(
— user9211845
您的数据输入为10行，但预计还会更多。是基于输入示例的预期
— akrun
@akrun：对不起，但是输出仅用于视觉表示。我需要了解获取此类输出的方法。

您可以从所需dput的数据集开始-这是第三个代码块。由于您似乎对输出内容满意，因此前面的代码似乎不相关。

希望这足以使您入门，继续下去，我需要一个预期的输出，看起来像是来自R的输出，以及有关如何计算变量的进一步说明。
