Hi I looked in the "writing R extensions" and also into package.skeleton, but could not find anything: I am looking for a skeleton or simple example on how to create a package which contains C++ code. I only want to implement one function, so nothing complicated. The idea is to use the package to make it easier to install the function on several Linux computers - no windows required at the moment.

Yes, the Rcpp package from CRAN. Start with
help("Rcpp-package", package="Rcpp")
Comments on where the documentation is not clear are welcome.
More about Rcpp is e.g. at http://dirk.eddelbuettel.com/code/rcpp.html

Hope that helps ... Thomas P.
