macro: conditional print based on number of values parameter

remainmack · Posted 11-29-2019 08:56 PM

Moving this from below thread to avoid confusion but I am trying to add a parameter for the maximum number of unique values for a character variable. If the number of unique values for the variable is less than or equal to the parameter, a frequency analysis is included in the macro presenting data for all unique values of the variable in question. If the number of unique values is large than the parameter, then only most frequent values for the given variable should be displayed. The default value of the parameter I am setting to 5 for now. The code to deal with this is at the bottom of my macro.

The issue I am having is 1) I don't know how to set both sides of the condition (greater or less than) for my third parameter and 2) set my default number within the macro (trying to set to 5). Any help would be wonderful as I am stuck.

%macro codebook(lib=,ds=,maxVal=);

%if &lib= BLANK | &ds = BLANK %then %do;
	%put &=lib;
	%put &=ds;
	%abort;
%end;


ods select variables;
proc contents data=&lib..&ds. out=_contents_  ; run;
proc format; 

value tfmt 

1 = 'NUM' 
2 = 'CHAR'; 

run;




data _null_;
	set _contents_ end=last;
	
	call symput('vname'||strip(put(_n_,best.)), strip(name));
	call symput('vtype'||strip(put(_n_,best.)), strip(put(type,tfmt.)));
	call symput('vlabel'||strip(put(_n_,best.)), strip(label));

	if last then call symput('nVars',strip(put(_n_,best.)));
run;






%do j = 1 %to &nVars.;
	title1 "Analysis of &&vlabel&j (Variable=%upcase(&&vname&j.)) ";
	%if &&vtype&j=NUM %then %do;
		
		%PUT Condition was Met on &&vtype&j;
		
		proc means data=&lib..&ds.;
		
		
			var &&vname&j.;
		run;
	%end;
	
	%else %if &&vtype&j=CHAR %then %do;
	
		proc freq data=&lib..&ds.;
			tables &&vname&j./out=freqtab;
		run;
		
		%let printALL=YES;
		
		
		
		data _null_;
			
			set freqtab;
			
			if _n_ > &maxVal. then
				call symput('printAll','NO');
			run;
	%end;
%end;

%mend;
	
%codebook(lib=out,ds=adsl,maxVal=4)	;

Do you know how to do it without the macro?

Show the code you would use to limit the output for the variable NAME from the SASHELP.CLASS dataset to 4 values. Then we can help you convert that into something that works inside your macro.

Maybe this:

%macro test2;



		ods output nlevels=nlev;
		proc freq data=sashelp.class nlevels;
			tables name/out=freqtab;
		run;

	

proc sql;

select nlevels into: max_lev from nlev;
quit;



		%put &max_lev;
		
		%if &max_lev. >= 10 %then %do;
			data a;
		
		
			set freqtab(obs=10);

	       
	       run;
					
		%end;
			
		%else %if &max_lev. < 10 %then %do;
			data a;
		
			if first.count then  ;
			set freqtab;

			run;
					
		%end;
			
			

%mend;
	
%test2	;

Something like this. I'll let you fix the titles issue.

%macro codebook(lib=,ds=,maxVal=);

%if &lib= BLANK | &ds = BLANK %then %do;
	%put &=lib;
	%put &=ds;
	%abort;
%end;


ods select variables;
proc contents data=&lib..&ds. out=_contents_  ; run;
proc format; 

value tfmt 

1 = 'NUM' 
2 = 'CHAR'; 

run;




data _null_;
	set _contents_ end=last;
	
	call symput('vname'||strip(put(_n_,best.)), strip(name));
	call symput('vtype'||strip(put(_n_,best.)), strip(put(type,tfmt.)));
	call symput('vlabel'||strip(put(_n_,best.)), strip(label));

	if last then call symput('nVars',strip(put(_n_,best.)));
run;






%do j = 1 %to &nVars.;
	title1 "Analysis of &&vlabel&j (Variable=%upcase(&&vname&j.)) ";
	%if &&vtype&j=NUM %then %do;
		
		%PUT Condition was Met on &&vtype&j;
		
		proc means data=&lib..&ds.;
		
		
			var &&vname&j.;
		run;
	%end;
	
	%else %if &&vtype&j=CHAR %then %do;
	    ods select none;
	    ods output nlevels=_nlev;
		proc freq data=&lib..&ds. NLEVELS;

thanks! Just saw this right after I posted mine 🙂

So I've implemented and tested but for some reason the output stops with the first variable in loop (and no errors). The proc freq additions at the bottom worked outside the macro for me. I am also trying to get the number of levels to not display in each print out (only output the data so I can grab the nLevels). I tried a workaround using proc sql directly from the variable but no luck.

options mprint symbolgen mlogic;
%macro codebook(lib=,ds=,maxVal=);

%if &lib= BLANK | &ds = BLANK %then %do;
	%put &=lib;
	%put &=ds;
	%abort;
%end;


ods select variables;
proc contents data=&lib..&ds. out=_contents_  ; run;
proc format; 

value tfmt 

1 = 'NUM' 
2 = 'CHAR'; 

run;




data _null_;
	set _contents_ end=last;
	
	call symput('vname'||strip(put(_n_,best.)), strip(name));
	call symput('vtype'||strip(put(_n_,best.)), strip(put(type,tfmt.)));
	call symput('vlabel'||strip(put(_n_,best.)), strip(label));

	if last then call symput('nVars',strip(put(_n_,best.)));
run;






%do j = 1 %to &nVars.;
	title1 "Analysis of &&vlabel&j (Variable=%upcase(&&vname&j.)) ";
	%if &&vtype&j=NUM %then %do;
		
		%PUT Condition was Met on &&vtype&j;
		
		proc means data=&lib..&ds.;
		
		
			var &&vname&j.;
		run;
	%end;
	
	%else %if &&vtype&j=CHAR %then %do;
	
		
	    ods select none;
		ods output nlevels=nlev;
		proc freq data=&lib..&ds. nlevels;
			tables &&vname&j./out=freqtab;
		run;
		
		
		proc sql;

		select nLevels into: nLevels from nlev;
		quit;
		
		%if &nLevels le &maxVal %then %do;
	
			
			proc print data=freqtab label;
			run;
		%end;
		%else %if &nLevels gt &maxVal %then %do;

		   data a;
		
		
			set freqtab(obs=&maxVal);

	       
	       run;


			proc print data=a label;
			run;
			
		%end;
		
		
	%end;
%end;

When you hit the first character variable you turn off all output.

ods select none;

You never turn it back on again. Add

ods select all;

Since you are making a dataset anyway you can just use the OBS= option

	%else %if &&vtype&j=CHAR %then %do;

ods select none;
ods output nlevels=nlev;
proc freq data=&lib..&ds. nlevels;
	tables &&vname&j./out=freqtab;
run;
ods select all;

options obs=&maxVal ;
proc print data=freqtab label;
run;
options obs=max;
			
	%end;

or use PROC SQL and the OUTOBS= option.

proc sql outobs=&maxVal ;
  select * from freqtab;
quit;

PS Do you want to add ORDER=FREQ to your PROC FREQ statement so that the &maxVAL most common values are printed?

remainmack · Posted 11-30-2019 05:18 PM

Thanks for your patience, Tom. I did add the order=FREQ. One final question as I am posting the code and one small snippet of output, I am trying to suppress the levels in the output of my program. You can see the levels number (in this example '2') before and after (actually for the next variable) the proc print of the proc freq. I generate those levels via proc sql now, but for some reason they show in the output. Why are they showing and how do I suppress? They are showing for any proc print of a proc freq object.

Code:

options mprint symbolgen mlogic;
%macro codebook(lib=,ds=,maxVal=);

%let maxVal=10;


%if &lib= BLANK | &ds = BLANK %then %do;
	%put &=lib;
	%put &=ds;
	%abort;
%end;


ods select variables;
proc contents data=&lib..&ds. out=_contents_  ; run;
proc format; 

value tfmt 

1 = 'NUM' 
2 = 'CHAR'; 

run;




data _null_;
	set _contents_ end=last;
	
	call symput('vname'||strip(put(_n_,best.)), strip(name));
	call symput('vtype'||strip(put(_n_,best.)), strip(put(type,tfmt.)));
	call symput('vlabel'||strip(put(_n_,best.)), strip(label));

	if last then call symput('nVars',strip(put(_n_,best.)));
run;






%do j = 1 %to &nVars.;
	title1 "Analysis of &&vlabel&j (Variable=%upcase(&&vname&j.)) ";
	%if &&vtype&j=NUM %then %do;
		
		%PUT Condition was Met on &&vtype&j;
		
		proc means data=&lib..&ds.;
		
		
			var &&vname&j.;
		run;
	%end;
	
	%else %if &&vtype&j=CHAR %then %do;
	
		
	    ods select none;
		*ods output nlevels=nlev;
		proc freq data=&lib..&ds. order=freq;
			tables &&vname&j./out=freqtab;
		run;
		ods select all;		
		
		proc sql;


*		select nLevels into: nLevels from nlev;
		select count(distinct(&&vname&j.)) into: nLevels from &lib..&ds.;
		quit;
		
		%if &nLevels le &maxVal %then %do;
	
			
			proc print data=freqtab label;
			run;
		%end;
		%else %if &nLevels gt &maxVal %then %do;

		 /*  data a;
		
		
			set freqtab(obs=&maxVal);

	       
	       run;


			proc print data=a label;
			run; */
			
			options obs=&maxVal ;
				proc print data=freqtab label;
			run;
			options obs=max;

If you don't want PROC SQL to print then tell it so by using the NOPRINT option.

proc sql noprint
  select nLevels format=32. into :nLevels trimmed from nlev;
  select count(distinct &&vname&j.) format=32. into :nLevels trimmed from &lib..&ds.;
quit;
