排序 R，时间序列数据

Question

我想在我当前的数据框中添加一个新列，它会根据足球比赛中的一系列事件添加一个新的序列号。

这是我当前的数据框

 head(test_P)
 index        team.name      possession_team.name  minute second period possession     type.name
1      5      Cardiff City         Cardiff City      0      0      1          2          Pass
2      6      Cardiff City         Cardiff City      0      2      1          2 Ball Receipt*
3      7      Cardiff City         Cardiff City      0      2      1          2         Carry
4      8      Cardiff City         Cardiff City      0      3      1          2          Pass
5      9      Cardiff City         Cardiff City      0      6      1          2 Ball Receipt*
6     10 Preston North End         Cardiff City      0      6      1          2          Duel
7     11 Preston North End         Cardiff City      0      6      1          2          Pass
8     12 Preston North End         Cardiff City      0      8      1          2 Miscontrol
9     13      Cardiff City         Cardiff City      0      8      1          2          Pass
10    14      Cardiff City         Cardiff City      0      9      1          2 Ball Receipt*
11    15      Cardiff City         Cardiff City      0      9      1          2         Cross
12    16 Preston North End         Cardiff City      0     10      1          2 Clearance
13    17      Cardiff City         Cardiff City      0     11      1          2          Pass
14    18      Cardiff City         Cardiff City      0     13      1          2 Ball Receipt*
15    19 Preston North End    Preston North End      0     13      1          3 Ball Recovery
16    20 Preston North End    Preston North End      0     13      1          3         Carry
17    21 Preston North End    Preston North End      0     21      1          3          Pass
18    22 Preston North End    Preston North End      0     22      1          3 Ball Receipt*.

但是，我想在 possession 之后添加一个名为 sequence 的附加列名称，它标记了 possession 的序号。

每个新的拥有都应该以值为 1 的序列开始

但是如果对方用 event/events 打破了这个序列并且控球值仍然相同，那么下次控球球队触球时应该是一个新的序列号，例如 2 或者如果多次中断3,4 等等

反对事件应使用与他们打破的事件相同的序列号进行编码

例如下面的数据

   index        team.name      possession_team.name  minute second period possession type.name sequence
1      5      Cardiff City         Cardiff City      0      0      1          2          Pass         1
2      6      Cardiff City         Cardiff City      0      2      1          2 Ball Receipt          1
3      7      Cardiff City         Cardiff City      0      2      1          2         Carry         1
4      8      Cardiff City         Cardiff City      0      3      1          2          Pass         1
5      9      Cardiff City         Cardiff City      0      6      1          2 Ball Receipt*         1
6     10 Preston North End         Cardiff City      0      6      1          2          Duel         1
7     11 Preston North End         Cardiff City      0      6      1          2          Pass         1
8     12 Preston North End         Cardiff City      0      8      1          2 Miscontrol            1
9     13      Cardiff City         Cardiff City      0      8      1          2          Pass         2
10    14      Cardiff City         Cardiff City      0      9      1          2 Ball Receipt          2
11    15      Cardiff City         Cardiff City      0      9      1          2         Cross         2
12    16 Preston North End         Cardiff City      0     10      1          2 Clearance             2
13    17      Cardiff City         Cardiff City      0     11      1          2          Pass         3
14    18      Cardiff City         Cardiff City      0     13      1          2 Ball Receipt          3
15    19 Preston North End    Preston North End      0     13      1          3 Ball Recovery         1
16    20 Preston North End    Preston North End      0     13      1          3         Carry         1
17    21 Preston North End    Preston North End      0     21      1          3          Pass         1
18    22 Preston North End    Preston North End      0     22      1          3 Ball Receipt          1

我已尝试将超前和滞后函数与 ifelse 语句结合使用，但似乎无法使数据正常工作

     test <- test  %>% mutate(P = ifelse(dplyr::lag(team.id)!=team.id & dplyr::lag(possession) == possession, dplyr::lag(seq_id) + 1,
                                                      ifelse(dplyr::lead(team.id)!=team.id & dplyr::lead(possession)!=possession , seq_id, 1)))

任何帮助将不胜感激，并为这个问题的不整洁表示歉意

Answer 1

以下内容感觉很老套，但可能会起作用。

逻辑如下：

生成一个 flip 变量，每次 team.name “翻转”时为 1/2，否则为 0。
生成cum_sum_flip，超过flip的累计和。添加 1 以使其从 1 而不是 0 开始。
通过从 cum_sum_flip 中取出 floor() 来生成 sequence，这样在每次翻转时，序列都会增加。

备注：

为了便于理解，我把中间变量留了下来，大家可以稍微巩固一下。
根据您的数据结构，您可能必须按 match 或其他方式分组，以确保当全新的比赛开始时，它会再次从 0 开始计数。
这个解决方案不是很稳健，并且对数据结构有一些假设。请检查边缘情况。

library(dplyr)

test_P %>% 
  mutate(flip = (lag(team.name) != team.name) %>% replace_na(0) * 1/2,
         .after = possession
  ) %>% group_by(possession) %>% 
  mutate(cum_sum_flip = cumsum(flip)+1, 
         sequence = floor(cum_sum_flip),
         .after = possession
  )

结果：

# A tibble: 18 x 11
# Groups:   possession [2]
   index team.name         possession_team.name minute second period possession cum_sum_flip sequence  flip type.name    
   <dbl> <chr>             <chr>                 <dbl>  <dbl>  <dbl>      <dbl>        <dbl>    <dbl> <dbl> <chr>
