What does the automatic variable named _N_ represent?
What is the automatic variable _n_? When you open a SAS data file in a data library, you will notice the observations are numbered at the first column. The automatic variable _n_ represents the observation numbers. This variable hidden in the DATA step is simple yet powerful in programming practice.
How do you combine variables in SAS?
To perform a one-to-one merge, use the MERGE statement without a BY statement. SAS combines the first observation from all data sets in the MERGE statement into the first observation in the new data set, the second observation from all data sets into the second observation in the new data set, and so on.
Can a single format statement be associated with multiple variables?
A single FORMAT statement can associate the same format with several variables, or it can associate different formats with different variables. If a variable appears in multiple FORMAT statements, SAS uses the format that is assigned last.
How to change the format of a variable in SAS?
By using the DATASETS procedure, you can change a variable’s format with the MODIFY statement and its subordinate FORMAT statement. You can change a variable’s format either to a SAS format or to a format that you have defined and stored, or you can remove a format. Here is the syntax for these statements:
How to disassociate a variable from a format statement?
To disassociate a format from a variable, use the variable in a FORMAT statement without specifying a format in a DATA step or in PROC DATASETS. In a DATA step, place this FORMAT statement after the SET statement. See Removing a Format. You can also use PROC DATASETS.
How to create user defined formats in SAS?
SAS Tutorials: User-Defined Formats (Value Labels) This SAS software tutorial shows how to create and assign your own variable formats (value labels) in SAS using PROC FORMAT. These formats are useful if you have numerically coded categorical variables and want to attach meaningful labels to those values.
