基于另一个值的重复序列

Question

我正在处理这样设置的数据结构：

数据

structure(list(ID = c(1147L, 1147L, 1147L, 1147L, 1147L, 1147L, 
1147L, 1147L, 1147L, 1147L, 1147L, 1147L, 4085L, 4085L, 4085L, 
4085L, 4085L, 4085L, 4085L), year = c(1L, 1L, 1L, 2L, 2L, 2L, 
3L, 3L, 3L, 4L, 4L, 4L, 1L, 1L, 1L, 2L, 2L, 2L, 3L), term = c(1L, 
3L, 5L, 1L, 3L, 5L, 1L, 3L, 5L, 1L, 3L, 5L, 1L, 3L, 5L, 1L, 3L, 
5L, 1L), reportedFY = c(NA, NA, NA, NA, NA, NA, NA, NA, NA, NA, 
NA, NA, NA, NA, NA, NA, NA, NA, NA), minFY = c(2016L, 2016L, 
2016L, 2016L, 2016L, 2016L, 2016L, 2016L, 2016L, 2016L, 2016L, 
2016L, 2019L, 2019L, 2019L, 2019L, 2019L, 2019L, 2019L)), class = "data.frame", row.names = c(NA, 
-19L))

ID  year    term    reportedFY  minFY
1147    1   1   NA  2016
1147    1   3   NA  2016
1147    1   5   NA  2016
1147    2   1   NA  2016
1147    2   3   NA  2016
1147    2   5   NA  2016
1147    3   1   NA  2016
1147    3   3   NA  2016
1147    3   5   NA  2016
1147    4   1   NA  2016
1147    4   3   NA  2016
1147    4   5   NA  2016
4085    1   1   NA  2019
4085    1   3   NA  2019
4085    1   5   NA  2019
4085    2   1   NA  2019
4085    2   3   NA  2019
4085    2   5   NA  2019
4085    3   1   NA  2019

每个ID（大约有9000个，每个重复12次，每年重复3次。我想做的是根据minFY为每个ID重复一个序列。所以ID 1147将有一个序列 2016,2017,2018,2019，其中每年重复 3 次。而 4085 将有一个序列 2019,2020,2021,2022，每个重复 3 次。

我一直在尝试使用与此类似的方法，但显然行不通：

prog_structure2$reportedFY <- rep(c(minFY, minFY+1, minFY+2, minFY+3), time=9306, each=3)

如有任何帮助，我们将不胜感激！

Answer 1

这应该适合你：

library(dplyr)
d <- data.frame('ID' = c(rep(1147, 12), rep(4085,12)), 
'year' =  rep(rep(1:4,each=3),2), 
'term' = rep(c(1,3,5),8),
'reportedFY' = NA, 
'minFY' = c(rep(2016, 12), rep(2019,12)))
 
 d <- d %>% group_by(ID) %>% mutate(reportedFY = rep(seq(first(minFY),(first(minFY)+3)),each = 3))

Answer 2

基础 R

df$reportedFY <- ave(df$minFY, df$ID, FUN = function(x) rep(min(x) + 0:3, each = 3))

     ID year term reportedFY minFY
1  1147    1    1       2016  2016
2  1147    1    3       2016  2016
3  1147    1    5       2016  2016
4  1147    2    1       2017  2016
5  1147    2    3       2017  2016
6  1147    2    5       2017  2016
7  1147    3    1       2018  2016
8  1147    3    3       2018  2016
9  1147    3    5       2018  2016
10 1147    4    1       2019  2016
11 1147    4    3       2019  2016
12 1147    4    5       2019  2016
13 4085    1    1       2019  2019
14 4085    1    3       2019  2019
15 4085    1    5       2019  2019
16 4085    2    1       2020  2019
17 4085    2    3       2020  2019
18 4085    2    5       2020  2019
19 4085    3    1       2021  2019
