| Date | Mon, 15 Aug 2011 11:42:41 +0100 |
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?
