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
