Constructor	Description
MixedDataBox(List<Node> variables, int numRows)	The variables here are used only to determine which columns are discrete and which are continuous; bounds checking is not done.
MixedDataBox(List<Node> variables, int numRows, double[][] continuousData, int[][] discreteData)	This constructor allows other data readers to populate the fields directly.

Constructor Details

MixedDataBox

public MixedDataBox(List<Node> variables,
 int numRows)

The variables here are used only to determine which columns are discrete and which are continuous; bounds checking is not done.

MixedDataBox

public MixedDataBox(List<Node> variables,
 int numRows,
 double[][] continuousData,
 int[][] discreteData)

This constructor allows other data readers to populate the fields directly.

Parameters:

variables - list of discrete and continuous variables

numRows - number of cases in the dataset

continuousData - continuous data

discreteData - discrete data

Method Details

serializableInstance

public static BoxDataSet serializableInstance()

Generates a simple exemplar of this class to test serialization.

numRows

public int numRows()

Specified by:

numRows in interface DataBox

Returns:

the number of rows in this continuousData box.

numCols

public int numCols()

Specified by:

numCols in interface DataBox

Returns:

the number of columns in this continuousData box.

set

public void set(int row,
 int col,
 Number value)

Sets the value at the given row/column to the given Number value. The value used is number.doubleValue().

Specified by:

set in interface DataBox

get

public Number get(int row,
 int col)

Specified by:

get in interface DataBox

Returns:

the Number value at the given row and column. If the value is missing (-99), null, is returned.

copy

public DataBox copy()

Specified by:

copy in interface DataBox

Returns:

a copy of this continuousData box.

like

public DataBox like()

Specified by:

like in interface DataBox

Returns:

a DataBox of type DoubleDataBox, but with the given dimensions.

addVariable

public void addVariable(Node variable)

viewSelection

public DataBox viewSelection(int[] rows,
 int[] cols)

Specified by:

viewSelection in interface DataBox

Returns:

this data box, restricted to the given rows and columns.

getContinuousData

public double[][] getContinuousData()

getDiscreteData

public int[][] getDiscreteData()
