This package shows some simple examples for the use of the deprecated classic API from the first implementation of Rcpp.
Note that the RcppClassic package has been deprecated since 2010, all new development should use the Rcpp package instead.
The Rcpp package provides a number of C++ classes that ease access to C++ from R. This comprises both passing parameters to functions, as well as returning results back from C++ to R.
Two APIs are supported. The first is an older API which was first introduced mostly in 2006 and extended in 2008. This interface is used by a few other packages and will be supported going forward in the RcppClassic-package package.
A second and newer API that was started in 2009 offers more functionality, see the Rcpp-package package.
The RcppExamples package provides some simple examples for use of Rcpp.
Dominick Samperi wrote the initial versions of Rcpp (and RcppTemplate) during 2005 and 2006. Dirk Eddelbuettel made some additions, and became maintainer in 2008. Dirk Eddelbuettel and Romain Francois have been extending Rcpp since 2009.
See the RcppExamples-package for examples of the recommended Rcpp API and Rcpp-package for documentation on the recommended API to extend R with C++ code, while the deprecated RcppClassic-package documents the older, deprecated API.
