Write XRFF (Advanced File Connectors)


Writes the values of all examples into an XRFF-file.


Writes values of all examples into an XRFF file which can be used by the machine learning library Weka. The XRFF format is described in the XrffExampleSource operator which is able to read XRFF files to make them usable with RapidMiner.
