To add leading zeros to the hour, minute, and second pairs in the given set of time values, you can use the following code:

times <- c("23:18:00", "15:02:00", "16:20:00", "16:40:00", "22:06:00", 
"18:03:00", "22:00:00", "19:33:00", "22:16:00", "0:33:00", "17:30:00", 
"22:25:00", "18:54:00", "4:41:00", "17:40:00", "1:00:00", "1:01:00", 
"18:23:00", "20:08:00", "1:50:00")

formatted_times <- format(as.POSIXct(times, format="%H:%M:%S"), "%H:%M:%S")

formatted_times

This code converts the time values to POSIXct format, and then converts them back to the desired time format (“%H:%M:%S”) with leading zeros added. The resulting formatted time values are stored in the variable formatted_times.
