The Factor type exposes the following members.

Constructors

	Name	Description
	Factor(Object)	Constructs a Factor instance from the given array of objects.
	Factor(Object, Int32)	Constructs a Factor instance from the given array of factor levels, and the given data array consisting of indices into the factor levels.
	Factor(Object, Object)	Constructs a Factor instance from the given array of objects, using the given factor levels.
	Factor(Object, String)	Constructs a Factor instance from the given array of objects.
	Factor(Object, Int32, String)	Constructs a Factor instance with the specified name from the given array of factor levels, and the given data array consisting of indices into the factor levels.
	Factor(Object, Object, String)	Constructs a Factor instance from the given array of objects, using the given factor levels.

Properties

	Name	Description
	Data	Gets the categorical data for this factor.
	Item	Gets the element at the given index.
	Length	Gets the length of the data vector for this factor.
	Levels	Gets the levels of this factor.
	Name	Gets and set the name of this factor.
	NumberOfLevels	Gets the number of levels in this factor.

Methods

	Name	Description
	Clone	Creates a deep copy of this Factor.
	DataToString	Returns a formatted string representation of the data of this factor.
	LevelsToString	Returns a formatted string representation of the levels of this factor.
	ToString	Returns a formatted string representation of this factor. (Overrides ObjectToString)

Operators

	Name	Description
	(Factor to Object)	Implicitly converts a factor into an array of objects.
	(Factor to String)	Implicitly converts a factor into an array of strings.

Fields

	Name	Description
	name_	The name of this vector.

Remarks

Factors are usually constructed from a data frame column using the GetFactor() method.
