The new MAXLEVELS= option in the TABLES statement in PROC FREQ enables you to specify the maximum number of variable levels to display in a one-way frequency table. If you pair this with the ORDER=FREQ option in the PROC FREQ statement, you can show the top n levels of a variable. The MAXLEVELS= option does not apply to the output data set, and it does not affect the computation of percentages, statistics, or tests for the one-way table.

The example code below illustrates this option.

data test;
   input x frq;
   datalines;
1 10
2 30
3 12
4 5
5 24
6 77
;
run;

proc freq data=test order=freq;
   tables x / maxlevels=3 out=new;
   weight frq;
run;

proc print data=new;
run;
