ParameterClass-class


ParameterClass is a class containing a list of sub class objects (i.e. constructed features, inhereted
from BaseClass). A ParameterClass object in a SetUpClass object defines which constructed features are computed 
from a DataClass object


Data quality issues such as missing values and outliers are often
interdependent, which makes preprocessing both time-consuming and leads to
suboptimal performance in knowledge discovery tasks. This package supports
preprocessing decision making by visualizing interdependent data quality issues
through means of feature construction. The user can define his own application
domain specific constructed features that express the quality of a data point
such as number of missing values in the point or use nine default features.
The outcome can be explored with plot methods and the feature constructed data
acquired with get methods.
