Truncated display of hour in R

I would like to create a vector of characters that will display all the possible Hours/Minutes of the day.

Hence, I would like to create a vector that looks like this

hours_mins = c("0:00",  "0:01",....,"5:09",  "5:10",  "5:11",  "5:12",  "5:14",  "5:15",..., "23:58", "23:59" )

However, my problem in creating this vector is that the hour displayed in hours_mins is not in the regular format, i.e. 00:00, or 05:09. Hence, how do I create a vector such as hours_mins with truncated display of the hour?

>Solution :

Here’s a base R solution:

sub("^0","", strftime(as.POSIXct("00:00", format="%H:%M")+seq(0,86380,by=60), format="%H:%M") )
