Title Seamless R and C++ Integration Version 0.11.2 Date 2014-06-06

Description The Rcpp package provides R functions as well as a C++ library which facilitate the integration of R and C++. R data types (SEXP) are matched to C++ objects in a class hierarchy. All R types are supported (vectors, functions, environment, etc...) and each type is mapped to a dedicated class. For example, numeric vectors are represented as instances of the Rcpp::NumericVector class, environments are represented as instances of Rcpp::Environment, functions are represented as Rcpp::Function, etc... The ``Rcpp-introduction' ' vignette provides a good entry point to Rcpp. Conversion from C++ to R and back is driven by the templates Rcpp::wrap and Rcpp::as which are highly flexible and extensible, as documented in the ``Rcpp-extending' ' vignette. Rcpp also provides Rcpp modules, a framework that allows exposing C++ functions and classes to the R level. The ``Rcpp-modules' ' vignette details the current set of features of Rcpp-modules. Rcpp includes a concept called Rcpp sugar that brings many R function
