Function Documentation

SEXP INTERNAL ( SEXP  x)
inline

Get function accessed via .Internal().

Parameters:
xPointer to a CXXR::Symbol (checked).
Returns:
If x is associated with a function invoked in R via .Internal(), then a pointer to the appropriate CXXR::BuiltInFunction, otherwise a null pointer.
void SET_INTERNAL ( SEXP  x,
SEXP  v 
)

Associate a Symbol with a .Internal() function.

Parameters:
xPointer to a CXXR::Symbol (checked).
vPointer to the CXXR::BuiltInFunction (checked) to be associated by this symbol. A null pointer is permissible, and signifies that any previous association of sym with a function is to be removed from the table.
