Hi folks
I want some observations (obs) by group (place) and time (timepoint)
data have;
input place $ timepoint obs;
datalines;
a 1.1 0
a 1.2 0
a 1.3 1
a 1.4 0
a 1.5 0
b 1.1 0
b 1.2 1
b 1.3 0
b 1.4 2
b 1.5 0
;
run;
data want;
set have;
...
run;
What I want is to retain the last obs by place to the dataset looks like this
Any idea on how to do this ?
data want;
set have;
by place;
retain retain_obs;
if first.place then retain_obs = .;
if obs ne 0 then retain_obs = obs;
run;
data want;
set have;
by place;
retain retain_obs;
if first.place then retain_obs = .;
if obs ne 0 then retain_obs = obs;
run;
Thanks a lot - nice and simple. Works like a charm 😀
