NAME

       Bio::Tools::PSort::SVMLoc::DataSet - A DataSet object for the Bio::Tools::PSort::SVMLoc
       Support Vector Machine.

SYNOPSIS

         use Bio::Tools::PSort::SVMLoc::DataSet;

         # Create a new dataset.
         $ds = new Bio::Tools::PSort::SVMLoc::DataSet(Label => 1,
                                           Data  => [ 0.12, 0.25, 0.33, 0.98 ]);

         # Retrieve/set the label.
         $label = $ds->label();
         $ds->label(1976);

         # Retrieve/set the attribute with an index of 0.
         $attr = $ds->attribute(0);
         $ds->attribute(0, 0.2621);

DESCRIPTION

       Bio::Tools::PSort::SVMLoc::DataSet is a representation of the datasets passed to
       Bio::Tools::PSort::SVMLoc object for training or classification.  Each dataset has an
       associated label, which classifies it as being part of a specific group.  A dataset object
       also has one or more key/value pairs corresponding to the attributes that will be used for
       classification.

CONSTRUCTORS

        $ds = new Bio::Tools::PSort::SVMLoc::DataSet(Label => 1,
                                          Data  => [ 0.12, 0.25, 0.33, 0.98 ]);

       The Bio::Tools::PSort::SVMLoc::DataSet constructor accepts two optional named parameters:
       Label and Data.  Label is used to set the class to which the dataset belongs, and Data is
       used to set any initial values.  Data should be an arrayref of numerical values.  Each
       value in the arrayref is assumed to have a key corresponding to its index in the array.

         ie) In the above example, 0.12 has a key of 0, 0.25 has a key of 1,
             0.33 has a key of 2, etc.

METHODS

         $label = $ds->label();
         $ds->label(1976);

       The label method is used to set or retrieve the DataSets label value.  Parameters and
       return values should be numeric values.

         $attr = $ds->attribute(0);
         $ds->attribute(0, 0.2621);

       The attribute method is used to set dataset attribute values.  If a single value is
       provided, the method will return the corresponding value.  If two value are provided, the
       method will set the first parameter to the value of the second.
