Detailed Description

This class defines a VTK interface to an embedded GNU R intepreter instance. An instance of the R interpreter is created when this class is instantiated. Additional instances of this class will share access the same R interpreter. The R interpreter will be shutdown when the application using this class exits.

Member Function Documentation

static vtkRInterface* vtkRInterface::New

(

)

[static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

static int vtkRInterface::IsTypeOf

(

const char *

name

)

[static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

virtual int vtkRInterface::IsA

(

const char *

name

)

[virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

static vtkRInterface* vtkRInterface::SafeDownCast

(

vtkObjectBase *

o

)

[static]

Reimplemented from vtkObject.

virtual vtkObjectBase* vtkRInterface::NewInstanceInternal

(

)

const [protected, virtual]

Reimplemented from vtkObject.

vtkRInterface* vtkRInterface::NewInstance

(

)

const

Reimplemented from vtkObject.

void vtkRInterface::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		[virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

int vtkRInterface::EvalRcommand	(	const char *	commandName,
		int	param
	)

Evaluate an R command on the embedded R interpreter that takes one integer argument.

int vtkRInterface::EvalRscript	(	const char *	string,
		bool	showRoutput = true
	)

Evaluate an R script given in string on the embedded R interpreter. Set showRoutput to turn on and off output from R.

int vtkRInterface::OutputBuffer	(	char *	p,
		int	n
	)

Provide a character buffer in p of length n. All output from the R interpreter instance will be written to p by default.

void vtkRInterface::AssignVTKDataArrayToRVariable	(	vtkDataArray *	da,
		const char *	RVariableName
	)

Copies vtkDataArray da into the R interpreter instance as a variable named RVariableName. If RVariableName already exists, it will be overwritten.

void vtkRInterface::AssignVTKArrayToRVariable	(	vtkArray *	da,
		const char *	RVariableName
	)

Copies vtkArray da into the R interpreter instance as a variable named RVariableName. If RVariableName already exists, it will be overwritten.

void vtkRInterface::AssignVTKTreeToRVariable	(	vtkTree *	tr,
		const char *	RVariableName
	)

Copies vtkTree tr into the R interpreter instance as a variable named RVariableName. If RVariableName already exists, it will be overwritten.

vtkTree* vtkRInterface::AssignRVariableToVTKTree

(

const char *

RVariableName

)

Copies the R variable RVariableName to the returned vtkDataArray. If the operation fails, the method will return NULL.

vtkDataArray* vtkRInterface::AssignRVariableToVTKDataArray

(

const char *

RVariableName

)

Copies the R variable RVariableName to the returned vtkDataArray. If the operation fails, the method will return NULL.

vtkArray* vtkRInterface::AssignRVariableToVTKArray

(

const char *

RVariableName

)

Copies the R variable RVariableName to the returned vtkArray. If the operation fails, the method will return NULL. The returned vtkArray is currently always a vtkDenseArray of type double.

vtkTable* vtkRInterface::AssignRVariableToVTKTable

(

const char *

RVariableName

)

Copies the R matrix or R list in RVariableName to the returned vtkTable. If the operation fails, the method will return NULL. If RVariableName is an R list, each list entry must be a vector of the same length.

void vtkRInterface::AssignVTKTableToRVariable	(	vtkTable *	table,
		const char *	RVariableName
	)

Copies the vtkTable given in table to an R list structure name RVariableName. The R list will be length of the number of columns in table. Each member of the list will contain a column of table.
