weka.filters.unsupervised.attribute.Copy

An instance filter that copies a range of attributes in the dataset. This is used in conjunction with other filters that overwrite attribute values during the course of their operation -- this filter allows the original attributes to be kept as well as the new attributes.

Valid options are:

 -R <index1,index2-index4,...> Specify list of columns to copy. First and last are valid indexes. (default none)

 -V Invert matching sense (i.e. copy all non-specified columns)
