Creating new variables and conditional processing

- [Instructor] In this section, I'll show you how to create and add new variables to the data table using a DATA step. In R, we typically use the dollar sign syntax to add a variable to our data frame. I'll how you how to do the same thing with a DATA step. And by the end of this section, I want to show you how to conditionally create a variable using syntax like if, else if, and else functions. To add a variable to a dataset, we're going to start with our DATA step, specify the name of the data table we're working with, and the same name in the set statement. Again, this overrides the existing data table with your changes. So here, I'm creating a new variable called wheelbase underscore plus underscore length, and I'm just adding together two variables in the cars dataset. And you can go ahead and add in as many variables as you want in a single DATA step. Moving on, let's go ahead and create variables conditionally now, and let's motivate this with an example. Suppose car…
