R 如何仅计算营业时间的“任务时间”

Question

有没有办法只计算工作时间的“任务时间”？工作时间周一至周五早八点至晚五点。示例：

使用

datediff()

：

预期结果：

示例任务时间：

# df %>%
#   select(v_v_initiated,v_v_complete)
                  v_v_initiated                v_v_complete

Answer 1

您可以采用另一个函数来计算某个时间间隔的营业时间（例如this。

首先，创建从开始到结束的日期序列，并按仅包含工作日进行过滤。

接下来，使用感兴趣的营业时间创建时间间隔（在本例中为“08:00”到“17:00”）。

确定每天的工作时间与您的时间有多少重叠。这样，如果时间从“09:05”开始，则该时间将用作一天的开始，而不是“08:00”。

最后，总结时间间隔，并确定工作日数（假设每天 9 小时）以及剩余的小时和分钟。

如果您想将此函数应用于数据框中的行，您可以使用

mapply

，如下所示：

df$business_hours <- mapply(calc_bus_hours, df$start_date, df$end_date)

希望这对您有帮助。

library(lubridate)
library(dplyr)

calc_bus_hours <- function(start, end) {
  my_dates <- seq.Date(as.Date(start), as.Date(end), by = "day")
  my_dates <- my_dates[!weekdays(my_dates) %in% c("Saturday", "Sunday")]
  
  my_intervals <- interval(ymd_hm(paste(my_dates, "08:00"), tz = "UTC"), ymd_hm(paste(my_dates, "17:00"), tz = "UTC"))
  
  int_start(my_intervals[1]) <- pmax(pmin(start, int_end(my_intervals[1])), int_start(my_intervals[1]))
  int_end(my_intervals[length(my_intervals)]) <- pmax(pmin(end, int_end(my_intervals[length(my_intervals)])), 
                                                      int_start(my_intervals[length(my_intervals)]))
  
  total_time <- sum(time_length(my_intervals, "minutes"))
  
  total_days <- total_time %/% (9 * 60)
  total_hours <- total_time %% (9 * 60) %/% 60
  total_minutes <- total_time - (total_days * 9 * 60) - (total_hours * 60)
  paste(total_days, "days,", total_hours, "hours,", total_minutes, "minutes")
}

calc_bus_hours(as.POSIXct("11/4/2020 9:05", format = "%m/%d/%Y %H:%M", tz = "UTC"), 
               as.POSIXct("11/9/2020 11:25", format = "%m/%d/%Y %H:%M", tz = "UTC"))

[1] "3 days, 2 hours, 20 minutes"

编辑：正如@DPH所提到的，假期和部分假期更加复杂。

您可以创建假期数据框并指示开放时间，允许部分假期（例如平安夜从上午 8:00 到中午）。

这是一个修改后的函数，应该给出可比较的结果。

library(lubridate)
library(dplyr)

holiday_df <- data.frame(
  date = as.Date(c("2020-12-24", "2020-12-25", "2020-12-31", "2020-01-01")),
  start = c("08:00", "08:00", "08:00", "08:00"),
  end = c("12:00", "08:00", "08:00", "08:00")
)

calc_bus_hours <- function(start, end) {
  my_dates <- seq.Date(as.Date(start), as.Date(end), by = "day")
  
  my_dates_df <- data.frame(
    date = my_dates[!weekdays(my_dates) %in% c("Saturday", "Sunday")], 
    start = "08:00", 
    end = "17:00"
  )
  
  all_dates <- union_all(
    inner_join(my_dates_df["date"], holiday_df),
    anti_join(my_dates_df, holiday_df["date"])
  ) %>%
    arrange(date)
  
  my_intervals <- interval(ymd_hm(paste(all_dates$date, all_dates$start), tz = "UTC"), 
                           ymd_hm(paste(all_dates$date, all_dates$end), tz = "UTC"))
  
  int_start(my_intervals[1]) <- pmax(pmin(start, int_end(my_intervals[1])), int_start(my_intervals[1]))
  int_end(my_intervals[length(my_intervals)]) <- pmax(pmin(end, int_end(my_intervals[length(my_intervals)])), 
                                                      int_start(my_intervals[length(my_intervals)]))
  
  total_time <- sum(time_length(my_intervals, "minutes"))
  
  total_days <- total_time %/% (9 * 60)
  total_hours <- total_time %% (9 * 60) %/% 60
  total_minutes <- total_time - (total_days * 9 * 60) - (total_hours * 60)
  paste(total_days, "days,", total_hours, "hours,", total_minutes, "minutes")
}
