Allows you to name or rename the factors and assign values for factor levels. If your factors could be continuous, use numeric levels; if your factors are categorical, use text levels. Continuous variables can take on any value on the measurement scale being used (for example, length of reaction time). In contrast, categorical variables can only assume a limited number of possible values (for example, type of catalyst).
