How do I add multiple conditions to an IF statement when subsetting my data?

christinagting0 — Tue, 21 Jun 2016 15:43:48 GMT

I am trying to subset my data based on keeping observations that contain "Comprehensive Assessment" and "Comprehensive AX - TM" in the variable named Description

My code doesn't work when I do this:

data keepca;
set allmergefinalanzio;
IF (description = "Comprehensive Assessment") AND (description = "Comprehensive Ax - TM");
run;

but it does seem to work when I do just one qualifyer like this:

data keepca;
set allmergefinalanzio;
IF (description = "Comprehensive Assessment");
run;

How can I have multiple conditions in one if statement to subset my data? what am I doing wrong?

thanks, new to sas!

In any programming language, "and" is a logical and, meaning both parts of the condition need to be true so that the whole condition will resolve to true.

What you are looking for is achieved by using "or" instead.

This worked:

data keepca;
set allmergefinalanzio;
IF (description = "Comprehensive Assessment") OR (description="Comprehensive Ax - TM");
run;
