        MLDataSet

A data set for holding general data (floats, ints, and strings)

**Note**
  this is intended to be a read-only data structure
  (i.e. after calling the constructor you cannot touch it)

__init__(self, data, nVars=None, nPts=None, nPossibleVals=None, qBounds=None, varNames=None, ptNames=None, nResults=1)
(Constructor)

source code  
Constructor

**Arguments**

  - data: a list of lists containing the data. The data are copied, so don't worry
        about us overwriting them.

  - nVars: the number of variables

  - nPts: the number of points

  - nPossibleVals: an list containing the number of possible values
                 for each variable (should contain 0 when not relevant)
                 This is _nVars_ long

  - qBounds: a list of lists containing quantization bounds for variables
           which are to be quantized (note, this class does not quantize
           the variables itself, it merely stores quantization bounds.
           an empty sublist indicates no quantization for a given variable
           This is _nVars_ long

  - varNames: a list of the names of the variables.
           This is _nVars_ long

  - ptNames: the names (labels) of the individual data points
     This is _nPts_ long
     
  - nResults: the number of results columns in the data lists.  This is usually
              1, but can be higher.
Overrides: object.__init__

_CalcNPossible(self, data)

source code  
calculates the number of possible values of each variable (where possible)

**Arguments**

   -data: a list of examples to be used

**Returns**

   a list of nPossible values for each variable

GetNamedData(self)

source code  
returns a list of named examples

**Note**

  a named example is the result of prepending the example
   name to the data list

GetInputData(self)

source code  
returns the input data

**Note**

  _inputData_ means the examples without their result fields
   (the last _NResults_ entries)
