What are the different ways to subset data in SAS?

Ways to Subset Data in SAS:

1. Using a WHERE statement: You can subset data in SAS using a WHERE statement in the DATA step. This allows you to filter the data based on conditions specified in the WHERE statement.
2. Using the IF-THEN/ELSE statement: Another way to subset data in SAS is by using the IF-THEN/ELSE statement in the DATA step. This allows for conditional subsetting of data based on specified criteria.
3. Using the SUBSET statement: The SUBSET statement in SAS can be used to create a subset of observations from a SAS data set based on a condition specified in the SUBSET statement.
4. Using PROC SQL: The PROC SQL procedure in SAS can be used to subset data by using SELECT statements with WHERE clauses to filter the data based on specified conditions.
5. Using the WHERE data set option: When reading data into SAS using a data set, you can specify a WHERE statement to subset the data as it is being read into SAS, allowing for efficient data subsetting.
