java.lang.Objectweka.filters.Filter
weka.filters.unsupervised.attribute.Remove
An instance filter that deletes a range of attributes from the dataset.
Valid filter-specific options are:
-R index1,index2-index4,...
Specify list of columns to delete. First and last are valid indexes.
(default none)
-V
Invert matching sense (i.e. only keep specified columns)

public boolean setInputFormat(Instances instanceInfo)
throws java.lang.Exception
setInputFormat in class FilterinstanceInfo - an Instances object containing the input instance
structure (any instances contained in the object are ignored - only the
structure is required).
java.lang.Exception - if the format couldn't be set successfullypublic boolean input(Instance instance)
input in class Filterinstance - the input instance
java.lang.IllegalStateException - if no input structure has been defined.public java.lang.String globalInfo()

public void setInvertSelection(boolean invert)
invert - the new invert settingpublic java.lang.String attributeIndicesTipText()
public java.lang.String getAttributeIndices()
public void setAttributeIndices(java.lang.String rangeList)
rangeList - a string representing the list of attributes. Since
the string will typically come from a user, attributes are indexed from
1. public void setAttributeIndicesArray(int[] attributes)
attributes - an array containing indexes of attributes to select.
Since the array will typically come from a program, attributes are indexed
from 0.public static void main(java.lang.String[] argv)
argv - should contain arguments to the filter: use -h for help
