Good afternoon Robert, Suppose you have your date and time in characters like this:
d.start = "2008-04-11" t.start = "22:00:00" d.end = "2008-04-12" t.end = "15:00:00" then use POSIXct to convert them to a unified time object: start <- as.POSIXct(paste(d.start, t.start)) end <- as.POSIXct(paste(d.end, t.end)) Then simply use seq() on your objects, here: OUT <- seq(start, end, by = 5) # 5 second steps. Hope this helps, (Robert) Michael Weylandt On Fri, Oct 14, 2011 at 12:02 PM, threshold <r.kozar...@gmail.com> wrote: > Dear R users, > > I got date and time as two separate characters > [1] "2008-04-11" > [1] "22:00:00" > > which correspond to my starting point in time domain. > > Now I need to produce series over, 5 sec epochs up to end point, say: > [1] "2008-04-12" > [1] "23:00:00" > > So something like > 2008-04-11 22:00:00 > 2008-04-11 22:00:05 > 2008-04-11 22:00:10 > . > . > . > 2008-04-12 23:00:00 > > Is there any strightforward way to do it?
