MakeCategoricalAt(Int32)	Marks the column at the specified index as containing categorical data.
MakeCategoricalAt<T>(Int32, Index<T>)	Marks the column at the specified index as containing categorical data.

Marks the column at the specified index as containing categorical data.

public DataFrame<R, C> MakeCategoricalAt(
	int index
)

Visual Basic

Public Function MakeCategoricalAt ( 
	index As Integer
) As DataFrame(Of R, C)

C++/CLI

public:
DataFrame<R, C>^ MakeCategoricalAt(
	int index
)

member MakeCategoricalAt : 
        index : int -> DataFrame<'R, 'C>

This method does not change the values in the column. It changes the representation to one for categorical data.

index is less than zero or greater than or equal to the number of columns in the data frame.

Marks the column at the specified index as containing categorical data.
