How Can I Get minute() to Return 00 instead of 0?












1















I am working on pulling time data from a dttm object in R and formatting it in HH:MM. I have been able to accomplish this using



paste(hour(datetime), minute(datetime), sep=':')


with one exception: when the minutes are less than 10. When I do this, the minute function just returns the minutes without a leading 0. For example:



library(lubridate)



datetime = ymd_hms('2018-11-18 14:00:00')



minute(datetime)


This gives an output of 



> minute(datetime)

[1] 0


I believe there are options using hms or other packages/functions, or by building an if-then, but I'd like to minimize dependencies and complexity and stick within the particulars of lubridate to accomplish my goal if at all possible.



(Note: I realize the same issue exists for hour(), but all the times I'm using are PM, so it's not as pressing in my case).






r lubridate

  • your data is having 14 hour 0 minutes so obviously it will give minute as 0 change it to 14:30 , it will give you output as 30

With format you can get your own custom date format after specifying - 



> format(datetime, "%M")

[1] "00"


OR



Thanks @Ronak - 



> sprintf("%02d", minute(datetime))

[1] "00"

Why are you doing all this extra work? Just get the time directly from your datetime (POSIXct) object.



strftime(datetime, "%H:%M")

# [1] "14:00"
