A new minor release Rcpp 0.11.2 is now on CRAN. 

A short blog post about it is at


and included as text (without links) below.

Thanks to very nice work by Kevin and JJ, it fixes a number of (small-ish)
things, adds a few new tricks and generally polishes matters around the
edges.  Tested quite profusely, so you should have no surprises.

As always, thanks for everybody for testing, suggestions and input.

   Rcpp 0.11.2

   A new minor release 0.11.2 of Rcpp is now on the CRAN network for GNU R,
   and binaries for Debian have also been uploaded.

   The release smoothes a few edges on both the Rcpp side itself, as well as
   on the interaction between Rcpp and R which since release 3.1.0 offers a
   few new features related to C++11.

   Kevin added a couple of neat extensions related to vectors, a new ListOf
   templated list class, as well as a new option to warn on implicit casts.
   We decided not to make this option the default as it may be too common in
   some packages. JJ took care of a few buglets related to the wonderful Rcpp
   Attributes. See the NEWS file section below for details, or the ChangeLog
   file in the package and on the Rcpp Changelog page. Note that the diffstat
   reported by CRANberries is very large as Kevin also committed a whitespace
   cleanup which touched almost all files.

   As before, we tested this release by building against all CRAN packages
   which depend upon Rcpp. In fact we did three such runs leading up to the
   release. Only one package was blacklisted (as I currently don't have CUDA
   set-up), two had what may be internal errors or tests which were too
   restrictive, sixteen suffered from missing packages or RGL devices --- but
   the remaining 202 packages all built and tested cleanly. Detailed results
   of those tests (and the scripts for it) are in the rcpp-logs repo GitHub.

   There are a number of other fixes, upgrades and other extensions detailed
   in NEWS file extract below, in the ChangeLog file in the package and on
   the Rcpp Changelog page.

    Changes in Rcpp version 0.11.2 (2014-06-06)

       * Changes in Rcpp API:

            * Implicit conversions, e.g. between NumericVector and
              IntegerVector, will now give warnings if you use #define
              RCPP_WARN_ON_COERCE before including the Rcpp headers.

            * Templated List containers, ListOf<T>, have been introduced.
              When subsetting such containers, the return is assumed to be of
              type T, allowing code such as ListOf<NumericVector> x;
              NumericVector y = x[0] + x[1] + x[2].

            * In a number of instances, returned results are protected and/or
              cast more carefully.

       * Changes in Rcpp Attributes

            * Trailing line comments are now stripped by the attributes
              parser. This allows the parser to handle C++ source files
              containing comments inline with function arguments.

            * The USE_CXX1X environment variable is now defined by the cpp11
              plugin when R >= 3.1. Two additional plugins have been added
              for use with C++0x (eg when using g++ 4.6.* as on Windows) as
              well as C++1y for compilers beginning to support the next
              revision of the standard; additional fallback is provided for

            * compileAttributes() now also considers Imports: which may
              suppress a warning when running Rcpp.package.skeleton().

   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, 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
