Hi

 

I have this data:

 

Person Status, january Status, february Status, march
A 2 3 2
B 4 4 4
C 3 2 3

 

And I need it transformed to this data:

Person Time Status
A January 2
A February 3
A March 2
B January 4
B February 4
B March 4
C January 3
C February 2
C March 3

 

Can anyone help me do this? Thanks a lot 🙂

Some of my work has noticed increased speed from running the transposition in a data step, but I'm unsure if that always holds.

 

data have;
input person $1. status_january status_february status_march;
datalines;
A 2 3 2
B 4 4 4
C 3 2 3
;
run;

data want (drop = status_: i);
	set have;
	array _s [*] status_:;
	do i = 1 to dim(_s);
		status = _s[i];
		time = propcase(scan(vname(_s[i]), -1, '_'));
		person = person;
		output;
	end;
run;

Now, do you actually have commas in your variable names? I substituted with underscores to make working code.

Nonetheless, here's my output:

person	status	time
A	2	January
A	3	February
A	2	March
B	4	January
B	4	February
B	4	March
C	3	January
C	2	February
C	3	March

 PROC TRANSPOSE is generally easier to understand.

This code will perform the task for you, under an important assumption.

 

proc transpose data=have out=want;
    by person;
run;

 

The assumption is that you are actually working with a valid SAS data set with valid SAS variable names; and not this apparent Excel file that you show.  Valid SAS variable names cannot have commas or spaces in the variable name, so you have to fix that. 

 

From now on, please provide data as working SAS data step code (examples and instructions) and not as Excel or Excel copy and paste into the window where you type your message.

Hi. Thanks for trying to help, but it doesn't seem to work.

(Yes, I am working with a proper SAS dataset - I just made up some variables names quickly).

 

When I use the code it just gives me an empty data set.

Do you know why?

Something about your actual real SAS data set is different than the one you showed. Please provide the data as working SAS data step code, as I explained earlier. Also please show the EXACT code you used.

We might have a chance of answering that if you include the log with the code an all of the notes from running the code. Copy the entire log text, on the forum open a text box using the </> icon that appears above the message window and paste all of the copied text.

Dude, this code is perfect. Thank you very much! (I don't actually have commas in my variable names, but I get your point ;-). )
