for removing rows that have missing values. An operation can process either only the numeric
columns or also the class label column.

Details
Preprocessing techniques defined with setpreprocessor() can be combined to a phase.

The user-defined S4 class definitions are stored in global environment and thus the function can not be used from an other package.
