public class SpreadSheetToWekaInstances
extends AbstractConversion

Generates a weka.core.Instances object from a SpreadSheet object.
If there are too many unique lables for a NOMINAL attribute, it gets turned into a STRING attribute (see 'maxLabels' property).

-logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
    The logging level for outputting errors and debugging output.
    default: WARNING
 

-max-labels <int> (property: maxLabels)
    The maximum number of labels that a NOMINAL attribute can have before it 
    is switched to a STRING attribute; use -1 to enforce STRING attributes.
    default: 25
    minimum: -1
