The trick is to realize times are stored internally in a special format, though they can be displayed in several ways based on the internal representation. The trick in doing comparison with times is to make certain what you are comparing with has also been put into the same internal time

Bingo! Thanks! I somehow couldn't find an example like that via google. Joe On Mon, Jan 2, 2017 at 1:35 PM, Roy Mendelssohn - NOAA Federal wrote: >> test > hm("10:00") > [1] FALSE FALSE TRUE TRUE >> test[test > hm("10:00")] > [1] "10H 30M 0S" "11H 0M 0S" > > -Roy > >

Thanks for the reply Roy! Perhaps you're showing me the way and I'm missing it - how would I subset to only 1030 and 1100, excluding 1000? It seems I would need to say, give me all time greater than 10:00, but the hours and minutes are in separate slots, which is throwing me off. Thanks again.

[R] Lubdridate: subset based on hour and minute

2017-01-02 Thread Joe Ceradini
Hi folks, I must be missing something obvious/painfully simple here How do I subset a time vector based on hours AND minutes? So, in this example, I want all time greater than 10:00, i.e., 10:30 and 11:00. I'm working with lubridate which separates the hours and minutes into separate slots.
