Hi
I would like to apply basevalue .like if id is 13 then 1,if id is 14 then 2 but in my code I am getting basevalue increamented for same id.Can anyone guide with the code.
(if first.id then basevalue=1;
basevalue+1;
dataset I want is like this
ID BASEVALUE
13 1
13 1
13 1
14 2
14 2
15 3
15 3
15 3
16 4
data have;
input ID ;
datalines;
13 1
13 1
13 1
14 2
14 2
15 3
15 3
15 3
16 4
;
data want;
set have;
by id;
if first.id then BASEVALUE+1;
run;
/*or*/
data want;
set have;
by id;
if lag(id) ne id then BASEVALUE+1;
run;
You're close ... combine your two statements:
if first.id then basevalue + 1;
data have;
input ID ;
datalines;
13 1
13 1
13 1
14 2
14 2
15 3
15 3
15 3
16 4
;
data want;
set have;
by id;
if first.id then BASEVALUE+1;
run;
/*or*/
data want;
set have;
by id;
if lag(id) ne id then BASEVALUE+1;
run;
Thank you 🙂
