I want to transpose the following table without using proc transpose:
Original Table:
ID facility
1 Swimming Pool
1 SPA
2 Gym room
2 restaurant
2 bar
3 Room
Expected Table:
ID facility_1 facility_2 facility_3
1 Swimming Pool SPA
2 Gym room restaurant bar
3 Room
The number of facilities for each ID is unknown.
Can someone please help me out?
data have;
length facility $20.;
infile cards dlm=',' dsd;
input ID facility;
cards;
1,Swimming Pool
1,SPA
2,Gym room
2,restaurant
2,bar
3,Room
;
run;
proc sql noprint;
SELECT max(nfac) INTO :nfac TRIMMED
FROM (
SELECT count(facility) AS nfac
FROM have
GROUP BY ID
)
;
quit;
data want;
set have;
by ID;
retain facility1-facility&nfac.;
array fac(&nfac.) $20. facility1-facility&nfac.;
if first.ID then do;
call missing(of fac(*));
i=1;
end;
else i+1;
fac(i)=facility;
if last.ID;
drop i facility;

I am going to transpose the dataset inside SAS enterprise miner using code editor, Howeve, it seems SAS enterprise miner does not support proc transpose.
data have;
length facility $20.;
infile cards dlm=',' dsd;
input ID facility;
cards;
1,Swimming Pool
1,SPA
2,Gym room
2,restaurant
2,bar
3,Room
;
run;
proc sql noprint;
SELECT max(nfac) INTO :nfac TRIMMED
FROM (
SELECT count(facility) AS nfac
FROM have
GROUP BY ID
)
;
quit;
data want;
set have;
by ID;
retain facility1-facility&nfac.;
array fac(&nfac.) $20. facility1-facility&nfac.;
if first.ID then do;
call missing(of fac(*));
i=1;
end;
else i+1;
fac(i)=facility;
if last.ID;
drop i facility;
run;
Try replacing the proc sql with the following data step :
data _NULL_;
set have(keep=ID);
by ID;
retain nfac;
if _N_=1 then nfac=0;
if first.ID then i=1;
else i+1;
if last.ID and i>nfac then do;
nfac=i;
call symputx("nfac", nfac);
end;
run;
