Instantiation

You can instantiate a CategoricalVariable object by calling its constructor. See the CategoricalVariable constructor summary.

Categories

Each of the possible values of a categorical variable is represented by an instance of type Category. Categories can be added to or removed from a given categorical variable, provided that it wasn't set as read-only by calling SetAsReadOnly. This condition can be verified by inspecting property IsReadOnly. Categories must be identifiable, both by their Code and by their Label. As a consequence, a category can be added only if, in the given categorical variable, no other category already exists having the same code or the same label. Furthermore, a category can be removed by passing its code to method Remove(Double), or its label to method Remove(String).

Use property NumberOfCategories to know how many categories are currently associated to a given variable. Property Categories lists category instances. Category codes, or labels, can be enumerated by inspecting, respectively, properties CategoryCodes and CategoryLabels.

You can verify if a category is in the variable by passing its code to method TryGet(Double, Category), or its label to method TryGet(String, Category).
