Rcpp 0.10.3
A new relase 0.10.3 of Rcpp is now on CRAN and in Debian.
This is the fourth release in the 0.10.* series, and further extends
and solidifies the excellent Rcpp attributes. A few other bugs were
fixed as well, and support for wide character strings has been added.
We once again tested this fairly rigorously by checking against 86 of
the 100 CRAN packages depending on Rcpp. All of these passed. So we do
not expect any issues with dependent packages, but one never knows.
The complete NEWS entry for 0.10.3 is below; more details are in the
ChangeLog file in the package and on the Rcpp Changelog page.
Changes in Rcpp version 0.10.3 (2013-03-23)
* Changes in R code:
* Prevent build failures on Windowsn when Rcpp is installed
in a library path with spaces (transform paths in the same
manner that R does before passing them to the build
system).
* Changes in Rcpp attributes:
* Rcpp modules can now be used with sourceCpp
* Standalone roxygen chunks (e.g. to document a class) are
now transposed into RcppExports.R
* Added Rcpp::plugins attribute for binding directly to
inline plugins. Plugins can be registered using the new
registerPlugin function.
* Added built-in cpp11 plugin for specifying the use of C++11
in a translation unit
* Merge existing values of build related environment
variables for sourceCpp
* Add global package include file to RcppExports.cpp if it
exists
* Stop with an error if the file name passed to sourceCpp has
spaces in it
* Return invisibly from void functions
* Ensure that line comments invalidate block comments when
parsing for attributes
* Eliminated spurious empty hello world function definition
in Rcpp.package.skeleton
* Changes in Rcpp API:
* The very central use of R API R_PreserveObject and
R_ReleaseObject has been replaced by a new system based on
the functions Rcpp_PreserveObject, Rcpp_ReleaseObject and
Rcpp_ReplaceObject which shows better performance and is
implemented using a generic vector treated as a stack
instead of a pairlist in the R implementation. However, as
this preserve / release code is still a little rough at the
edges, a new #define is used (in config.h) to disable it
for now.
* Platform-dependent code in Timer.cpp now recognises a few
more BSD variants thanks to contributed defined() test
suggestions
* Support for wide character strings has been added
throughout the API. In particular String, CharacterVector,
wrap and as are aware of wide character strings
Thanks to CRANberries, you can also look at a diff to the previous
release 0.10.2. 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
