我想在组中的两个值之间填入“NAs”，其中状态为第一个值。该组是“标签”字段，我想在“状态”字段中填写“NA”。
这就是我所拥有的：
datetime title label status option_title
1 2016-08-06 Pursuit status: AIG Active1 <NA>
2 2016-08-06 What is the current stage of this Pursuit? AIG <NA> 1 - Opportunity Review
3 2016-08-31 What is the current stage of this Pursuit? AIG <NA> 2 - Solution Review
4 2016-12-13 What is the current stage of this Pursuit? AIG <NA> 4 - Submit Proposal
5 2016-11-14 Pursuit status: Allianz Active1 <NA>
6 2016-10-27 What is the current stage of this Pursuit? Allianz <NA> Pre-Qualification
7 2017-05-18 What is the current stage of this Pursuit? Allianz <NA> 1 - Opportunity Review
8 2017-05-18 What is the current stage of this Pursuit? Allianz <NA> Pre-Qualification
9 2017-08-24 Pursuit status: Allianz Inactive1 <NA>
10 2016-10-27 What is the current stage of this Pursuit? Allianz <NA> Pre-Qualification
11 2016-11-14 Pursuit status: Allianz Active2 <NA>
12 2016-12-19 What is the current stage of this Pursuit? Allianz <NA> 1 - Opportunity Review
13 2017-04-14 What is the current stage of this Pursuit? Allianz <NA> 2 - Solution Review
这就是我想要的：
datetime title label status option_title
1 2016-08-06 Pursuit status: AIG Active1 <NA>
2 2016-08-06 What is the current stage of this Pursuit? AIG Active1 1 - Opportunity Review
3 2016-08-31 What is the current stage of this Pursuit? AIG Active1 2 - Solution Review
4 2016-12-13 What is the current stage of this Pursuit? AIG Active1 4 - Submit Proposal
5 2016-11-14 Pursuit status: Allianz Active1 <NA>
5 2016-10-27 What is the current stage of this Pursuit? Allianz Active1 Pre-Qualification
7 2017-05-18 What is the current stage of this Pursuit? Allianz Active1 1 - Opportunity Review
8 2017-05-18 What is the current stage of this Pursuit? Allianz Active1 Pre-Qualification
9 2017-08-24 Pursuit status: Allianz Inactive1 <NA>
10 2016-10-27 What is the current stage of this Pursuit? Allianz Inactive1 Pre-Qualification
11 2016-11-14 Pursuit status: Allianz Active2 <NA>
12 2016-12-19 What is the current stage of this Pursuit? Allianz Active2 1 - Opportunity Review
13 2017-04-14 What is the current stage of this Pursuit? Allianz Active2 2 - Solution Review
有办法做到这一点吗？我认为最好的方法是获取第一个状态的日期和第二个状态的日期，并填写第一个状态之间的所有值。

tidyr方法：
您似乎已经解决了排序问题，因此这里有代码来复制数据集的最小示例。
df_orig <-
read.table(text = "
label status
AIG Active1
AIG <NA>
AIG <NA>
AIG <NA>
Allianz Active1
Allianz <NA>
Allianz <NA>
Allianz <NA>
Allianz Inactive1
Allianz <NA>
Allianz Active2
Allianz <NA>
Allianz <NA>
", header = TRUE, stringsAsFactors = FALSE) %>%
mutate(status = sub("<NA>", NA, status)) # to turn the "<NA>" to active NA's
> str(df_orig) 'data.frame': 13 obs. of 2 variables: $ label : chr "AIG" "AIG" "AIG" "AIG" ... $ status: chr "Active1" NA NA NA ...
填写'空缺'
df_filled <-
df_orig %>%
fill(status)
结果：
> df_filled label status 1 AIG Active1 2 AIG Active1 3 AIG Active1 4 AIG Active1 5 Allianz Active1 6 Allianz Active1 7 Allianz Active1 8 Allianz Active1 9 Allianz Inactive1 10 Allianz Inactive1 11 Allianz Active2 12 Allianz Active2 13 Allianz Active2
