Dear all,
I have the following dataset
ID | REGION | NUMTYPE |
NY | us;ne | 1015; 10x16 |
BO | us;ne | 1015; 10x17 |
ID | nonus | 1018 |
I would like to add another column "REGION_NUMTYPE" which has all the combinations of region and num type per row separated by the ";"
ID | REGION | NUMTYPE | REGION_NUMTYPE |
NY | us;ne | 1015; 10x16 | us1015; us10x16;ne1015;ne10x16 |
BO | us;ne | 1015; 10x17 | us1015; us10x17;ne1015;ne10x17 |
ID | nonus | 1018 | nonus1018 |
Is there a simple way to do this ? Many Thanks for your help
You can also trying using Hash to be more dynamic.
data have;
input ID :$ REGION :$20. NUMTYPE :$&20.;
cards4;;;;
NY us;ne 1015; 10x16
BO us;ne 1015; 10x17
ID nonus 1018
;;;;
data want;
set have;
length region_numtype $ 100;
array re(10) /*arbituary dimension*/ $10 _temporary_;
array num(10) $10 _temporary_;
do i=1 by 1 while (not missing (scan(region,i,';')));
re(i)=scan(region,i,';');
do j=1 by 1 while (not missing (scan(numtype,j,';')));
num(j)=scan(numtype,j,';');
region_numtype=catx(';',region_numtype,cats(re(i),num(j)));
end;
end;
drop i j;
run;
