RunClass-class


RunClass is an class contain ReportClass and AnalysisClass objects as separate lists.
A RunClass object is the output of running the main function preproviz() and can be
studied with either get or plot methods.


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.
