Dear All,

I would like to keep all the observations in one day (which it is
divideded in time intervals), if a variable takes value 1 at least in
one of the time intervals.

However, if I type:

keep data if s1==1 I will obatian only the time intervals and not the whole day.

Do you have any suggestion on how to do?

Thanks,
Katia
