Do you want each number in "Date" to be repeated once (as in your
example) or appear 48 times (so that you start over every 1440
rows, as in your request).
For the former,
rep(c(1:30),each=48)
fills the first 1440 rows.

I want to add identifier column (Date) to a time series data
frame. I want
to name the "Date" column be from 1 to 30 every 1440 rows.
Say I have a data like this (I simply my actual data here):
$dat
ID Var
1 1
2 4
3 6
4 7
5 7
6 8
How can I add identifier column (Date) from 1 to 3 every 2 rows
and have
output like this:
ID Var Date
1 1 1
2 4 1
3 6 2
4 7 2
5 7 3
6 8 3
Thanks,
