A new release Rcpp 0.11.5 arrived on CRAN on Friday -- my bad for forgetting
to announce it then.

A short blog post about it is at


and included as text (without links) below.

This release represents contributions from a number of people--but JJ in
particular is responsible for most of the changes.  As always, thanks to
everybody for testing, suggestions and input.

On behalf of Rcpp Core,  Dirk

   Rcpp 0.11.5

   The new release 0.11.5 of Rcpp just reached the CRAN network for GNU R,
   and a Debian package has also been be uploaded.

   Rcpp has become the most popular way of enhancing GNU R with C++ code.
   As of today, 345 packages on CRAN depend on Rcpp for making analyses go
   faster and further; BioConductor adds another 41 packages, and casual
   searches on GitHub suggests dozens mores.

   This release continues the 0.11.* release cycle, adding another large
   number of small bug fixes, polishes and enhancements. Since the
   previous release in January, we incorporated a number of pull requests
   and changes from several contributors. This time, JJ deserves a special
   mention as he is responsible for a metric ton of the changes listed
   below, making Rcpp Attributes even more awesome. As always, you can
   follow the development via the GitHub repo and particularly the Issue
   tickets and Pull Requests. And any discussions, questions, ...
   regarding Rcpp are always welcome at the rcpp-devel mailing list.

   See below for a detailed list of changes extracted from the NEWS file.

    Changes in Rcpp version 0.11.5 (2015-03-04)

     * Changes in Rcpp API:

         * An error handler for tinyformat was defined to prevent the
           assert() macro from spilling.

         * The Rcpp::warning function was added as a wrapper for

         * The XPtr class was extended with new checked_get and release
           functions as well as improved behavior (throw an exception
           rather than crash) when a NULL external pointer is

         * R code is evaluated within an R_toplevelExec block to prevent
           user interrupts from bypassing C++ destructors on the stack.

         * The Rcpp::Environment constructor can now use a supplied parent

         * The Rcpp::Function constructor can now use a supplied
           environment or namespace.

         * The attributes_hidden macro from R is used to shield internal
           functions; the R_ext/Visibility.h header is now included as

         * A Rcpp::print function was added as a wrapper around

     * Changes in Rcpp Attributes:

         * The pkg_types.h file is now included in RcppExports.cpp if it
           is present in either the inst/include or src.

         * sourceCpp was modified to allow includes of local files (e.g.
           #include "foo.hpp"). Implementation files (.cc; .cpp)
           corresponding to local includes are also automatically built if
           they exist.

         * The generated attributes code was simplified with respect to
           RNGScope and now uses RObject and its destructor rather than
           SEXP protect/unprotect.

         * Support addition of the rng parameter in Rcpp::export to
           suppress the otherwise automatic inclusion of RNGScope in
           generated code.

         * Attributes code was made more robust and can e.g. no longer

         * Version 3.2 of the Rtools is now correctly detected as well.

         * Allow 'R' to come immediately after '***' for defining embedded
           R code chunks in sourceCpp.

         * The attributes vignette has been updated with documentation on
           new features added over the past several releases.

     * Changes in Rcpp tests:

         * On Travis CI, all build dependencies are installed as binary
           .deb packages resulting in faster tests.

   Thanks to CRANberries, you can also look at a diff to the previous
   release As always, even fuller details are on the Rcpp Changelog page
   and the Rcpp page which also leads to the downloads page, the
   browseable doxygen docs and zip files of doxygen output for the
   standard formats. A local directory has source and documentation too.
   Questions, comments etc should go to the rcpp-devel mailing list off
   the R-Forge page.
