If then statement with ranges of variables

abdulla — Sun, 28 Feb 2021 18:11:07 GMT

Hi I have the following data

I want to create a column "want" in which if TIS is equal to any of the value in columns A1 to A8. I tried the following but I did not get the value I want for "Want" column.

Data want,

set have;

if TIS=(A1--A8) then want=1;

else want=0;

run;

TIS	A1	A2	A3	A4	A5	A6	A7	A8	want
7372	7323								0
5149	5122	5064							0
1541	4213	4953	4225	1541	5141	3341			1
3341	3577	3572	7372	7373	7379				0
2098	2099	2043	2041	2045	2024	2098	5149	5143	1
4953	4911	6719							0

Try this

data have;
input TIS A1 A2 A3 A4 A5 A6 A7 A8;
infile datalines missover;
datalines;
7372 7323                                    
5149 5122 5064                               
1541 4213 4953 4225 1541 5141 3341           
3341 3577 3572 7372 7373 7379                
2098 2099 2043 2041 2045 2024 2098 5149 5143 
4953 4911 6719                               
run;

data want;
   set have;
   array a{*} A1--A8;
   if tis in a then want = 1;
   else want = 0;
run;

Result:

TIS   A1   A2   A3   A4   A5   A6   A7   A8   want 
7372  7323 .    .    .    .    .    .    .    0 
5149  5122 5064 .    .    .    .    .    .    0 
1541  4213 4953 4225 1541 5141 3341 .    .    1 
3341  3577 3572 7372 7373 7379 .    .    .    0 
2098  2099 2043 2041 2045 2024 2098 5149 5143 1 
4953  4911 6719 .    .    .    .    .    .    0

With a proper data structure, this is extremely simple:

proc transpose
  data=have
  out=long (where=(col1 ne .))
;
by tis;
var a:;
run;

data want;
set long;
where tis = col1;
by tis;
if last.tis;
run;
