Kevin added a couple of neat
extensions related to vectors, a new
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
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
IntegerVector, will now give warnings if you use
#define RCPP_WARN_ON_COERCEbefore including the Rcpp
ListOf, have been
introduced. When subsetting such containers, the return is assumed
to be of type T, allowing code such as
x; NumericVector y = x + x + x
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.
USE_CXX1Xenvironment 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
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
