r - Create a time series with a row every 15 minutes

Question

I'm having trouble creating a time series (POSIXct or dttm column) with a row every 15 minutes.

Something that will look like this for every 15 minutes between Jan 1st 2015 and Dec 31st 2016 (here as month/day/year hour:minutes):

1/15/2015 0:00
1/15/2015 0:15
1/15/2015 0:30
1/15/2015 0:45
1/15/2015 1:00

A loop starting date of 01/01/2015 0:00 and then adding 15 minutes until 12/31/2016 23:45?

Does anyone has an idea of how this can be done easily?

Answer 1

Little bit easier to read

library(lubridate)
seq(ymd_hm('2015-01-01 00:00'),ymd_hm('2016-12-31 23:45'), by = '15 mins')
