WebbIn general, a categorical variable with k k levels / categories will be transformed into k−1 k − 1 dummy variables. Regression model can be fitted using the dummy variables as the predictors. In R using lm () for regression analysis, if the predictor is set as a categorical variable, then the dummy coding procedure is automatic.
