英文:
Convert hours and minutes into minutes
问题
I have a vector of event times in the form of hours, minutes, and seconds. Now I wish to convert all of these times into minutes. For example, 01:02:18 would become 62 minutes.
My data:
times"01:02:18" "01:47:37" "01:18:48" "01:32:54" "01:09:41" "01:50:30"
Code I tried but it did not work:
time = format(strptime(matchtime,"%H:%M:%S"),'%M')
Guessing there is something that could be done by adding the hours and minutes. However, I am unsure on how to do that as well.

如果我们想提取分钟和小时
library(lubridate)
v1 <- hms(times)
v1@hour * 60 + v1@minute
[1] 62 107 78 92 69 110
或者包括秒
period_to_seconds(hms(times))/60
[1] 62.30000 107.61667 78.80000 92.90000 69.68333 110.50000
英文:

period_to_seconds(hms(times))/60[1] 62.30000 107.61667 78.80000 92.90000 69.68333 110.50000

在基本的R中：
difftime(strptime(matchtime, "%T"), strptime('0:0:0', '%T'), units = 'min')时间差异（以分钟为单位）[1] 62.30000 107.61667 78.80000 92.90000 69.68333 110.50000
同样的效果：
as.numeric(strptime(matchtime, "%T") - strptime('0:0:0', "%T"), 'mins')[1] 62.30000 107.61667 78.80000 92.90000 69.68333 110.50000
编辑
使用data.table：
as.numeric(data.table::as.ITime(matchtime))/60[1] 62.30000 107.61667 78.80000 92.90000 69.68333 110.50000
英文:
in base R:
difftime(strptime(matchtime,"%T"), strptime('0:0:0','%T'), units = 'min')Time differences in mins[1] 62.30000 107.61667 78.80000 92.90000 69.68333 110.50000
same as:
as.numeric(strptime(matchtime,"%T") - strptime('0:0:0', "%T"),'mins')[1] 62.30000 107.61667 78.80000 92.90000 69.68333 110.50000
Edit
using data.table:
as.numeric(data.table::as.ITime(matchtime))/60[1] 62.30000 107.61667 78.80000 92.90000 69.68333 110.50000

你可以使用 as.difftime 并将单位设置为 mins。
as.difftime(times, units = "mins")#以分钟为单位的时间差#[1] 62.30000 107.61667 78.80000 92.90000 69.68333 110.50000
要忽略秒数，请使用 floor。
floor(as.difftime(times, units = "mins"))#以分钟为单位的时间差#[1] 62 107 78 92 69 110
数据
times <- c("01:02:18", "01:47:37", "01:18:48", "01:32:54", "01:09:41", "01:50:30")
英文:
You can use as.difftime and set the units to mins.
as.difftime(times, units = "mins")#Time differences in mins#[1] 62.30000 107.61667 78.80000 92.90000 69.68333 110.50000
To ignore the seconds use floor.
floor(as.difftime(times, units = "mins"))#Time differences in mins#[1] 62 107 78 92 69 110
Data
times <- c("01:02:18", "01:47:37", "01:18:48", "01:32:54", "01:09:41", "01:50:30")
