    public class WekaAccumulatedError
extends adams.flow.transformer.AbstractTransformer
    Generates plot containers from an evaluation object's predictions. The predictions are first sorted according to their error, smallest to largest, and then plot containers are created with the RMSE being accumulated.

    Input/output:
    - accepts:
       weka.classifiers.Evaluation
    - generates:
       adams.flow.container.SequencePlotterContainer


    Valid options are: 

    -D (property: debug)
    If set to true, scheme may output additional info to the console.
 
    -name <java.lang.String> (property: name)
    The name of the actor.
    default: AccumulatedError
 
    -annotation <adams.core.base.BaseText> (property: annotations)
    The annotations to attach to this actor.
    default:
 
    -skip (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
 
    -plot-name <java.lang.String> (property: plotName)
    The name for the plot.
    default: Plot
