The Rcpp package provides C++ classes that greatly facilitate interfacing C or C++ code in R packages using the .Call() interface provided by R.
Rcpp provides matching C++ classes for a large number of basic R data types. Hence, a package author can keep his data in normal R data structures without having to worry about translation or transfering to C++. At the same time, the data structures can be accessed as easily at the C++ level, and used in the normal manner.
The mapping of data types works in both directions. It is as straightforward to pass data from R to C++, as it is it return data from C++ to R. The following two sections list supported data types.
