选择并过滤从凌晨 03:00 到次日凌晨 03:00 的数据数据

Question

我正在尝试为日期和 id 的每个组合（凌晨 3 点到第二天凌晨 3 点）查找在 03:00:00 和第二天 03:00:00 之间发生的第一个“ON”记录。

    #dummy data
df <- tibble::tribble(
       ~id, ~code, ~start_day, ~hhmmss,       ~end_time,
  "7050-1",               "ON",   20200227,      "000000", 20200227002400,
  "7050-1",             "SNOOZE",   20200227,        "002400", 20200227003400,
  "7050-1",              "OFF",   20200227,        "003400", 20200227003545,
  "7050-1",               "ON",   20200227,        "003545", 20200227004815,
  "7050-1",             "SLP",   20200227,        "004815", 20200227021400,
  "7050-1",             "SLP",   20200227,       "021400", 20200227073415,
  "7050-1",               "ON",   20200227,       "073415", 20200227164515,
  "7050-1",               "ON",   20200228,      "025936", 20200227045936,
   "265-1",               "ON",   20200227,      "000000", 20200227002400,
   "265-1",             "SNOOZE",   20200227,      "164515", 20200227165515,
   "265-1",              "OFF",   20200227,      "165515", 20200228025936,
   "265-1",               "ON",   20200228,      "023536", 20200228025536,
  "265-1",               "OFF",   20200228,      "025536", 20200228003000,
  "265-1",               "ON",   20200228,       "03000", 20200228035936,
  "265-2",               "OFF",   20200228,      "000000", 20200228180000,
  "265-2",               "OFF",   20200228,      "180000", 20200228235959,
  "265-2",               "ON",   20200229,       "000000", 20200229020000,
  )

这是我目前的尝试

df %>%
  mutate(
    time = format(strptime(hhmmss, format = "%H%M%S"), format = "%H:%M:%S"),
    time = hms::as.hms(time, format = "%H:%M:%S") ,
    date = ymd(start_day) ) %>%
  group_by(date,id) %>%
  filter(time >= hms::as.hms("02:59:59", format = "%H:%M:%S") & code == "ON")

但我不应该使用这样的过滤器，因为我丢失了265-2record。这是我的愿望输出。 (** 265-2 记录发生在班次 28-02-28 03:00:00 和 28-02-29 03:00:00 之间，并且应该分配给日期 28/02 而不是 29/02 。希望很清楚

  id     code  date   time        

 7050-1 ON     20200227     07:34:15 
 265-1  ON     20200228     03:00:00 
 265-2  ON     20200228     00:00:00

idk，可能我没看懂你的逻辑，希望对你有帮助

df %>% 
   mutate(date = ymd(start_day),
          time = format(strptime(hhmmss, format = "%H%M%S"), format = "%H:%M:%S"),
          time = hms::as.hms(time, format = "%H:%M:%S")) %>% 
   mutate(new_date = as_datetime(glue::glue('{date} {time}')) - hours(3),
          new_date = as_date(new_date)) %>% 
   filter(code == "ON")
# A tibble: 8 x 8
  id     code  start_day hhmmss end_time date       time   new_date  
  <chr>  <chr>     <dbl> <chr>     <dbl> <date>     <drtn> <date>
