12.3.57 PhysicalData

   A PhysicalData object specifies the layout of the physical data to be used for mining, and if appropriate, the roles the various data columns play, via subclassing. The data referenced by a physical data object can be used in many capacities: model building, scoring, lift computation, statistical analysis, etc.

   PhysicalData supports specification of any data definable through a Class or set of Attributes (e.g., files, tables, and star schema).

   source

   The source attribute identifies the specific data to be used for data mining. It typically consists of a Table (from the Relational Package) or a File. Unless a specific subset of attributes is listed, all source attributes are taken as the usable physical data. If source is NULL, the attributes may be associated with one or more Class instances.
