Try this: fit <- glm (wealth_indicator ~ factor (ranking) + age_in_years + factor (ranking) * age_in_years) The factor () command will make sure that R knows that your variable is categorical. This is especially useful if your categories are indicated by integers, otherwise glm will interpret the variable as continuous.
