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 functions
into C++. Sugar takes advantage of lazy evaluation and expression templates
to achieve great performance while exposing a syntax that is much nicer
to use than the equivalent low-level loop code. The "Rcpp-sugar" vignette
gives an overview of the feature.
.
Rcpp attributes provide a high-level syntax for declaring C++
functions as callable from R and automatically generating the code
required to invoke them. Attributes are intended to facilitate both
interactive use of C++ within R sessions as well as to support R
package development. Attributes are built on top of Rcpp modules and
their implementation is based on previous work in the inline package.
.
Many examples are included, and around 891 unit tests in 430 unit
test functions provide additional usage examples.
.
An earlier version of Rcpp, containing what we now call the 'classic Rcpp
API' was written during 2005 and 2006 by Dominick Samperi. This code has
been factored out of Rcpp into the package RcppClassic, and it is still
available for code relying on the older interface. New development should
always use this Rcpp package instead.
.
Additional documentation is available via the paper by Eddelbuettel and
Francois (2011, JSS) paper and the book by Eddelbuettel (2013, Springer);
see 'citation("Rcpp")' for details.
