-
COMPRESS
-
begins display of the next one-way frequency table on the same page as the preceding one-way table if there is enough space
to begin the table. By default, the next one-way table begins on the current page only if the entire table fits on that page.
The COMPRESS option is not valid with the PAGE option.
-
DATA=SAS-data-set
-
names the SAS data set to be analyzed by PROC FREQ. If you omit the DATA= option, the procedure uses the most recently created
SAS data set.
-
FORMCHAR(1,2,7)='formchar-string'
-
defines the characters to be used for constructing the outlines and dividers for the cells of crosstabulation table displays.
The formchar-string should be three characters long. The characters are used to draw the vertical separators (1), the horizontal separators (2),
and the vertical-horizontal intersections (7). If you do not specify the FORMCHAR= option, PROC FREQ uses FORMCHAR(1,2,7)='|-+'
by default. Table 38.5 summarizes the formatting characters used by PROC FREQ.
Table 38.5: Formatting Characters Used by PROC FREQ
The FORMCHAR= option can specify 20 different SAS formatting characters used to display output; however, PROC FREQ uses only
the first, second, and seventh formatting characters. Therefore, the proper specification for PROC FREQ is FORMCHAR(1,2,7)=
'formchar-string'.
Specifying all blanks for formchar-string produces crosstabulation tables with no outlines or dividers—for example, FORMCHAR(1,2,7)=' '. You can use any character
in formchar-string, including hexadecimal characters. If you use hexadecimal characters, you must put an x after the closing quote. For information about which hexadecimal codes to use for which characters, see the documentation
for your hardware.
See the CALENDAR, PLOT, and TABULATE procedures in the
Base SAS Procedures Guide for more information about form characters.
-
NLEVELS
-
displays the “Number of Variable Levels” table, which provides the number of levels for each variable named in the TABLES statements. See the section Number of Variable Levels Table for details. PROC FREQ determines the variable levels from the formatted variable values, as described in the section Grouping with Formats.
-
NOPRINT
-
suppresses the display of all output. You can use the NOPRINT option when you only want to create an output data set. See
the section Output Data Sets for information about the output data sets produced by PROC FREQ. Note that the NOPRINT option temporarily disables the Output
Delivery System (ODS). For more information, see Chapter 20: Using the Output Delivery System.
Note: A NOPRINT option is also available in the TABLES statement. It suppresses display of the crosstabulation tables but allows display of the requested statistics.
-
ORDER=DATA | FORMATTED | FREQ | INTERNAL
-
specifies the order of the variable levels in the frequency and crosstabulation tables, which you request in the TABLES statement.
The ORDER= option can take the following values:
|
Value of ORDER=
|
Levels Ordered By
|
|
DATA
|
Order of appearance in the input data set
|
|
FORMATTED
|
External formatted value, except for numeric variables with no explicit format, which are sorted by their unformatted (internal)
value
|
|
FREQ
|
Descending frequency count; levels with the most observations come first in the order
|
|
INTERNAL
|
Unformatted value
|
By default, ORDER=INTERNAL. The FORMATTED and INTERNAL orders are machine-dependent. The ORDER= option does not apply to missing
values, which are always ordered first.
For more information about sort order, see the chapter on the SORT procedure in the
Base SAS Procedures Guide and the discussion of BY-group processing in
SAS Language Reference: Concepts.
-
PAGE
-
displays only one table per page. Otherwise, PROC FREQ displays multiple tables per page as space permits. The PAGE option
is not valid with the COMPRESS option.
