fun asDiscrete(variable: String, label: String? = null, orderBy: String? = null, order: Int? = null, levels: List<Any>? = null): MappingMeta
The function converts a column to a discrete scale and allows you to specify the order of its values. It is similar to the factor() function from R but works differently - there is no data transformation.
