DESCRIPTION
This module examines columns in a MutableTable and, for appropriate columns which contain nominal values, converts these single columns into multiple columns -- one for each possible value of the attribute.Detailed Description: If the input MutableTable implements the ExampleTable interface, only columns marked as inputs and outputs will be converted. Otherwise, all columns containing nominal values will be converted. Through a property of the module, the user can select whether the generated columns are double or boolean.Data Handling: This module modifies its input data; each relevant nominal column may be replaced with an arbitrary number of new ones. In addition, columns with blank labels are assigned default ones.
