Rcpp 0.7.3

A quick nine days after release 0.7.2 of Rcpp, our R / C++ interface classes, Romain and I are happy to roll out a new version 0.7.3. It has been uploaded to CRAN and Debian, and mirrors should have the new versions shortly. As before, my local page is also available for downloads and some more details.

This release combines a number of under-the-hood fixes and enhancements with one bug fix:

• The Rcpp:::LdFlags() helper function to dynamically provide linker options for packages using Rcpp now defaults to static linking on OS X as well. For installation from source dynamic linking always worked, but not for binary installation (as e.g. from CRAN). As on the other platforms, this default can be overridden. Thanks to the phylobase team for patient help in tracking this down.
• Accessing various types via [] should now be faster due to some enhancements in the internal representations.
• configure now has a command-line option (as well as an environment variable) to select support for the draft of the upcoming C++0x standard.
• A new function Rcpp.package.skeleton(), modelled after package.skeleton() in R itself, helps to set up a new package with support for using Rcpp.
• A number of other minor tweaks and improvements...

As always, full details are in the ChangeLog on the Rcpp page which also leads to the downloads, the browseable doxygen docs and zip files of doxygen output for the standard formats. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page
