= SAS Freq =

A procudure for printing one-way frequency tables up to n-way crosstabs.

----



== Usage ==

To display frequencies of variables, try:

{{{
proc freq data=LIBREF.TABLE order=freq;
  tables VARLIST;
run;
}}}

To list unique values, add the `nlevel` option to the procedure. 



=== Tables Statement ===

The '''`TABLES`''' statement creates a table for each variable specified in `VARLIST`.

To create a crosstab, try:

{{{
proc freq data=LIBREF.TABLE;
  tables STUBVAR*BANNERVAR;
run;
}}}

To suppress certain aspects of the frequency table, specify the corresponding suppression option. For example, to suppress cumulative frequencies, try:

{{{
proc freq data=LIBREF.TABLE order=freq;
  tables VARLIST / nocum;
run;
}}}

The options are:

||'''Option'''||'''Meaning'''                              ||
||`nocum`     ||suppress cumulative percentages            ||
||`nopercent` ||suppress cell percentages                  ||
||`norow`     ||suppress row percentages                   ||
||`nocol`     ||suppress column percentages                ||
||`crosslist` ||trigger nested list display for crosstabs  ||
||`list`      ||as above and includes `STUBVAR` on each row||



=== By Statement ===

The `BY` statement specifies one or more variables for which the `PROC FREQ` should be split.

----



== Tables Out ==

To store the frequencies displayed on a table, try:

{{{
proc freq data=LIBREF.TABLE order=freq;
  tables VARLIST / nocum out=LIBREF.NEWTABLE;
run;
}}}

`NEWTABLE` will contain the enw variables `COUNT` and `PERCENT`.

----



== Plot ==

To plot the frequencies percentages displayed on a table, try:

{{{
ods graphics on;
ods select freqplot;
proc freq data=LIBREF.TABLE order=freq;
  tables VARLIST / plots=freqplot(orient=horizontal scale=percent);
run;
}}}

To plot a crosstab with percentages, try:

{{{
ods graphics on;
ods select freqplot;
proc freq data=LIBREF.TABLE order=freq;
  tables STUBVAR*BANNERVAR / plots=freqplot(groupby=row orient=horizontal scale=grouppercent);
run;
}}}
