How to convert multiple records of one observation to a single record (condense it)

[mcalde33]

I need to make table A into Table b:

Question 1: Convert the multiple record per patient table to one record per patient

Table A Emp Id Jan Feb March April May June  1001 0 1 0 0 1 . 1001 . 0 0 0 0 0 1001 . 0 . 1 0 0 1001 0 1 0 0 . 0 1001 1 1 0 0 0 1 1002 1 1 1 1 0 0 1002 0 0 0 0 0 1 1003 1 1 . 1 0 0 1003 . 0 0 0 0 0 1003 0 0 . . 0 . 1004 . 1 0 0 0 0 1004 1 1 0 0 0 0 1004 1 . 0 0 0 0 1004 0 1 1 1 0 0

Table B Emp Id Jan Feb March April May June 1001 1 1 0 1 1 1 1002 1 1 1 1 0 1 1003 1 1 0 1 0 0 1004 1 1 1 1 0 0

This is my code so far:

OPTION PS= 58 LS= 72 NODATE NONUMBER;


DATA DM2022.Patients;
      SET patientsdata;
      By emplid;


Run;
   
        
PROC PRINT data= patients NOOBS;
      title 'Table B';
RUN;

[Reeza]

Take the maximum of each column grouping by ID

proc means data=dm2022.patients noprint NWAY;
class emplID;
var Jan--June;
output out=grouped_data max = ;
run;

I have questions about your code though...

Is your data/set statement backwards in the code you posted? And then no libraries reference in the print although it is assigned it to a library?

The options specified at the top of the code are usually seen in older SAS code that used the listing output not HTML one. Some of those do not apply to ODS HTML if that is the destination (displayed results file format).

Yes the SET "patientsdata" is referencing a temp dataset with the data as shown in table a

It's not working because the data doesn't exist though - not an issue with the code. 

What is the name of the input data set?

Please show a proc contents on that data, e.g.

proc contents data=patientsData;
run;

The code you posted is not relevant to the question being asked, but if it doesn't work then the next steps will not work. 

[mcalde33]

This is what im using to "set" the data.

DATA Patients;
INPUT EmpID 1-4 Jan 6 Feb 8 March 10 April 12 May 14 June 16;

DATALINES;
1001 0 1 0 0 1 .
1001 . 0 0 0 0 0
1001 . 0 . 1 0 0
1001 0 1 0 0 . 0
1001 1 1 0 0 0 1
1002 1 1 1 1 0 0
1002 0 0 0 0 0 1
1003 1 1 . 1 0 0

*display results from summarization step;
proc print data=grouped_data;
run;

The above works as expected. I'm not sure what the rest of your code was intended to do, therefore not sure if it's needed.

I don't know what you were inten

[mcalde33]

this worked and I got this:
Table B

EmpID _TYPE_ _FREQ_ Jan Feb March April May June
1001 1 5 1 1 0 1 1 1
1002 1 2 1 1 1 1 0 1
1003 1 3 1 1 0 1 0 0
1004 1 4 1 1 1 1 0 0


But i dont want the columns type and freq.
Where do I add the NOFREQ? and NOTYPE?

[Reeza]

proc means data=patients noprint NWAY;
class empID;
var Jan--June;
output out=grouped_data (drop = _freq_ _type_) max = ;
run;

Use a dataset drop option to drop the variables in the proc means step.
