fun asDiscrete(variable: String, label: String? = null, orderBy: String? = null, order: Int? = null, levels: List<Any>? = null): MappingMeta
Marks a numeric variable as categorical. The plot will use a discrete scale for the aesthetic mapping. It is similar to the factor() function from R but works differently - there is no data transformation.
