如何在 R 中创建漏斗视图

Question

我有一个具有以下结构的 dataframe。

ProdID         Date                    class          price        set
PD-10011       2021-05-01 10:12:16     Regular        1000         ZR
PD-10712       2021-05-02 18:12:06     Premium        1000         ZR
PD-10213       2021-05-02 16:02:59     Premium        1000         ZR
PD-10814       2021-05-03 17:12:06     Premium        1000         RS
PD-10315       2021-05-04 19:10:11     Other          1000         RR
PD-10616       2021-05-04 13:18:14     Expired        1000         ZR
PD-10617       2021-05-04 15:14:19     Regular        1000         ZR

我需要考虑以下条件，利用数据框创建一个漏斗视图：

5 月 21 日，应根据日期自动填充月份。 如果有多个月份的记录，则应按月份降序排列。 在这里， Total是该特定月份的 Total 唯一 ProdID 计数。 Regular是将 class 作为“Regular”以及“Premium”行的类似逻辑的 ProdID 的计数和总和。 miscellaneous行是具有“常规”和“高级”以外的类别的 ProdID 的计数。 RS (Premium)是 class 为“Premium”且设置为“RS”的那些的计数和总和。

May-21           Count of ProdID       Percentage Count       Sum of Price        Percentage Sum
Total            7                     100.00%                7000                100.00%
Regular          2                     28.57%                 2000                28.57%
Premium          3                     42.85%                 3000                42.85%
miscellaneous    2                     28.57%                 2000                28.57%
RS (Premium)     1                     33.33%                 1000                33.33%

在 StackOverflow 上，您应该展示自己解决问题的尝试。 话虽如此，这应该让你开始：

library(tidyverse)
library(lubridate)
library(janitor)

df <- tibble::tribble(
