Count frequency in the columns?

ybz12003 — Mon, 05 Feb 2018 17:49:29 GMT

Hello:

I would like to count the group frequency of the two columns "Analysis" and "Product" in test1 table below. Please advice how to approach. Thanks.

data test1; 
      infile datalines dlm='|'; 
  input name : $20. Analysis : $100. Product : $100.; 
datalines;                  
Ali| Cleft Lip +/- Palate|  LABETOLOL|   
Ali| Cleft Lip +/- Palate|  ATENOLOL|   
Ali| VSDs (Excludes VSDavc)|  ATENOLOL|  
Ali| VSDs (Excludes VSDavc)|  FLUCONAZOLE| 
Carol| Choanal Atresia|  LEVOTHYROXINE SODIUM|   
Carol| Cleft Lip +/- Palate|  ATENOLOL|   
Carol| Intestinal Atresia/Stenosis|  EPHEDRA|  
Malyn| TGA +/- DORV|  ALBUTEROL SULFATE|  
Malyn|  TOF +/- PA, DORV -TGA|  BUTALBITAL| 
Malyn| Esoph Atresia +/- TEF|  FLONASE|   
; 

proc sort data=test1; by analysis; run;

The result I am looking for is:

Analysis Count

Cleft Lip +/- Palate 3

VSDs (Excludes VSDavc) 2

Choanal Atresia 1

Intestinal Atresia/Stenosis 1

TGA +/- DORV 1

TOF +/- PA, DORV -TGA 1

Esoph Atresia +/- TEF 1

Product

LABETOLOL 1

ATENOLOL 2

FLUCONAZOLE 1

LEVOTHYROXINE SODIUM 1

EPHEDRA 1

ALBUTEROL SULFATE 1

BUTALBITAL 1

FLONASE

Please post example code in a code box opened with either the {I} or running man icon.

Please.

Do you really want a record of data with no values (the blank dataline)?

Is the ORDER of the appearance important? If so you might specify the rules.

If I wanted the output in descending order of frequency I would start with

proc freq data=test1 order=freq;
   tables analysis product /nocum nopercent;
run;

I don't know how to post example code in a code box opened with either the {I} or running man icon. I add { } before and after my codes. Does it help?

How to generate a permeant SAS dataset instead of in the "result viewer"? Is there a way to output in one table? Thanks.

You should learn how. It makes it easier on us to help you.

And please try reading the documentation BEFORE asking questions.

The first example in PROC FREQ:

Example 3.1 Output Data Set of Frequencies

Proc freq can create one output data set per tables request which would be for one variable. You could append two data sets to get one though.

HOW would you use the single data set with both variables summarized? There can be significant issues in what needs to be done to use such a summarized set depending on exact usage.

You can use ODS to get both into one table, demoed below
