Detailed Description

C++ wrapper around calls (LANGSXP SEXP)

This represents calls that can be evaluated

Rcpp::Language::Language ( )

Definition at line 26 of file Language.cpp.

Rcpp::Language::Language ( SEXP lang )

Attempts to convert the SEXP to a call

Exceptions:

not_compatible if the SEXP could not be converted to a call using as.call

Definition at line 28 of file Language.cpp.

Here is the call graph for this function:

Rcpp::Language::Language ( const std::string & symbol ) [explicit]

Creates a call using the given symbol as the function name

Parameters:

symbol symbol name to call

Language( "rnorm" ) makes a SEXP similar to this (expressed in R) > as.call( as.list( as.name( "rnorm") ) ) > call( "rnorm" )

Definition at line 41 of file Language.cpp.

References Rcpp::RObject::setSEXP().

Here is the call graph for this function:

Rcpp::Language::Language ( const Symbol & symbol ) [explicit]

Creates a call using the given symbol as the function name

Parameters:

symbol symbol name to call

Language( Symbol("rnorm") ) makes a SEXP similar to this: > call( "rnorm" )

Definition at line 45 of file Language.cpp.

References Rcpp::RObject::setSEXP().

Here is the call graph for this function:

Rcpp::Language::Language ( const Function & function ) [explicit]

Creates a call to the function

Parameters:

function function to call

SEXP Rcpp::Language::eval ( )

eval this call in the global environment

Definition at line 74 of file Language.cpp.

Referenced by Rcpp::binary_call< T1, T2, OUT >::operator()(), Rcpp::unary_call< T, OUT >::operator()(), and Rcpp::fixed_call< OUT >::operator()().

SEXP Rcpp::Language::eval ( SEXP env )

eval this call in the requested environment

Definition at line 78 of file Language.cpp.

References Rcpp::RObject::m_sexp, and Rcpp::internal::try_catch().

Here is the call graph for this function:

Language & Rcpp::Language::operator= ( const Language & other )

References Rcpp::RObject::asSexp(), and Rcpp::RObject::setSEXP().

Here is the call graph for this function:

void Rcpp::Language::setFunction ( const Function & function )

sets the function

Definition at line 64 of file Language.cpp.

References Rcpp::RObject::m_sexp, and R_NilValue.

void Rcpp::Language::setSymbol ( const std::string & symbol )

Creates a call to the given symbol using variable number of arguments

Parameters:

symbol	symbol
...Args	variable length argument list. The type of each argument must be wrappable, meaning there need to be a wrap function that takes this type as its parameter

For example, Language( "rnorm", 10, 0.0 ) will create the same call as > call( "rnorm", 10L, 0.0 )

10 is wrapped as an integer vector using wrap( const& int ) 0.0 is wrapped as a numeric vector using wrap( const& double ) ... sets the symbol of the call

Definition at line 55 of file Language.cpp.

void Rcpp::Language::setSymbol ( const Symbol & symbol )

sets the symbol of the call

Definition at line 59 of file Language.cpp.

References Rcpp::RObject::m_sexp, and R_NilValue.

void Rcpp::Language::update ( ) [private, virtual]

Reimplemented from Rcpp::RObject.
