An abstract class that inherits from the base class stream::DSC and provides the common functions needed to interface MOA clusterers.

Usage

DSC_MOA(...)

Arguments

...

Further arguments (currently ignored).

Details

DSC_MOA is a subclass of stream::DSC for MOA-based clusterers. DSC_MOA classes operate in a different way in that the centers of the micro-clusters have to be extracted from the underlying Java object. This is done by using rJava to perform method calls directly in the JRI and converting the multi-dimensional Java array into a local R data type.

Note: The formula interface is currently not implemented for MOA-based clusterers. Use stream::DSF to select features instead.
