How to transpose from long to wide with duplicate values

sas_student1 — Wed, 03 Feb 2021 15:49:55 GMT

Hello,

I hope the folks here can assist:

I have a dataset with provider hours of operation. I would like to transpose the database so that the day of the week is a column with the time as the value for each provider and program by row. I have a sample of what I have the dataset look like right now and what I would like it to look like (there is SAS code too to create the dataset). You will note that for some of the providers the day of the week duplicates (there are two Mondays, two Thursdays and two Fridays by provider and program), in that case I don't mind having another columns for each (see second table of what the table can look like).

Suggestions on how to achieve this, please.

Thanks!

Dataset looks like this:

Prov	Prog	Day	Time
24	166	FRI	10:00AM-5:00PM
24	166	MON	10:00AM-8:00PM

The last 2 steps are there to bring the columns in order.

@Kurt_Bremser fantastic!! Just what I need.

Almost there.

I need to do a "by" statement by both prov and prog. So in your code I added prog to the by statement.

However, I don't really understand how the last data _null_ is working to add the prog item too.

That is since I have an extract column for prog the data _null_ statement, which is great as I do need to order by the day, isn't working. Recommendation on how to add the prog item to that statement as well?

Thanks!

Here's where you need to add the variable:

proc sort data=test;
by prov prog day;
run;

data t2;
set test;
by prov prog day;
if first.day
then seq = 1;
else seq + 1;
d = input(day,inwd.);
lab = cats(day,seq);
run;

proc transpose data=t2 out=wide (drop=_name_);
by prov prog;
id d seq;
idlabel lab;
var time;
run;

proc sql;
create table vars as
  select name, label
  from dictionary.columns
  where libname = "WORK" and memname = "WIDE" and upcase(name) not in ("PROV","PROG")
  order by name
;
quit;

data _null_;
call execute("data want;");
call execute("retain Prov Prog");
do until (d1);
  set vars end=d1;
  call execute(" "!!name);
end;
call execute(";set wide;rename");
do until (d2);
  set vars end=d2;
  call execute(" "!!cats(name,"=",label));
end;
call execute(";run;");
stop;
run;

Untested, posted from my tablet.

@Kurt_Bremser fantastic thanks!

I was playing around on adding prog was close but no cigar!

Thank you!
