public class DoubleVectorLabelParser
extends NumberVectorLabelParser<DoubleVector>

Provides a parser for parsing one point per line, attributes separated by whitespace.

Several labels may be given per point. A label must not be parseable as double. Lines starting with "#" will be ignored.

An index can be specified to identify an entry to be treated as class label. This index counts all entries (numeric and labels as well) starting with 0.
