The ANES dataset has two variables for age: dem_agegrp (the respondent’s age in 13 categories) and XYdem_age4cat (age in four categories). This latter variable is a variable that I created using the original age variable. Recode the original age variable to create a new variable that will be identical to this four-category age variable.
