I have a data format like below:
id time1 time2 time3
1 1
2
3
2 1
2
3
The time was on diagonal for each people, but I want to convert it to a long format with one time variable and different times under it:
ID Time
1 1
1 2
1 3
2 1
2 2
3 3
Does anyone know how to do it? Thank you!
data have;
input id time1 time2 time3 ;
cards;
1 1 . .
. . 2 .
. . . 3
2 1 . .
. . 2 .
. . . 3
;
data want;
set have(rename=(id=_id));
retain id .;
if not missing(_id) then id=_id;
time=coalesce(of time1-time3);
keep id time;
run;
I would try:
data want; set have; time = max(time1,time2,time3); drop time1-time3; run;
Do your second and third rows really have blank ID values?
data have;
input id time1 time2 time3 ;
cards;
1 1 . .
. . 2 .
. . . 3
2 1 . .
. . 2 .
. . . 3
;
data want;
set have(rename=(id=_id));
retain id .;
if not missing(_id) then id=_id;
time=coalesce(of time1-time3);
keep id time;
run;
