Gabor this is better than using
x = seq(ISOdate(2006,1,1, 0, 0, 0), by = "15 min", length.out=35040)
this works but your code below is exactly what I needed instead of almost.
thankyou very much

Try this:
library(chron)
t1 <- chron("1/1/2006", "00:00:00")
t2 <- chron("12/31/2006", "23:45:00")
deltat <- times("00:15:00")
tt <- seq(t1, t2, by = times("00:15:00"))
Note that if you have some data and your intention is simply to
create the index for it so you can create a zoo or zooreg object
I would like a sequence of dates with a time step of 15 minutes
starting:
1/1/2006 00:00:00 - 12/31/2006 23:45:00
function(x) {
chron(sub(" .*", "", x), gsub(".* (.*)", "\\1:00", x))
}
this is the piece of code I use to read in zoo objects
for any help I would be grateful I have tried sequenc
