Function Documentation

SEXP Rf_allocSExp

(

SEXPTYPE

t

)

Create an object of a type derived from CXXR::ConsCell.

The object is created with null car, tag and tail pointers.

Parameters:

t	The SEXPTYPE of the required object. Must be one of LISTSXP, LANGSXP, DOTSXP or BCODESXP (not checked).

Returns:

Pointer to the created object.

void SET_TAG	(	SEXP	x,
		SEXP	y
	)

Set the tag of a CXXR::ConsCell.

Parameters:

x	Pointer to a CXXR::ConsCell (checked).
y	Pointer a CXXR::RObject representing the new tag of the CXXR::ConsCell.

SEXP SETCAR	(	SEXP	x,
		SEXP	y
	)

Set the 'car' value of a CXXR::ConsCell.

Parameters:

x	Pointer to a CXXR::ConsCell (checked).
y	Pointer a CXXR::RObject representing the new value of the list car.

Returns:

y.
