Rcpp 0.12.1: First boat load of fixes!

September 10, 2015

(This article was first published on Thinking inside the box , and kindly contributed to R-bloggers)

The first updated in the 0.12.* series of Rcpp is now on the CRAN network for GNU R this morning, and I will push a Debian package. This follows the 0.12.0 release from late July which started to some serious new features.

Rcpp has become the most popular way of enhancing GNU R with C++ code. As of today, 461 packages on CRAN depend on Rcpp for making analyses go faster and further.

This release once again features contributions from a number of new contributors, with Florian Plaza Oñate and Dan Dillon joining the fray with several pull requests each. Kurt Hornik also helped with a fix for a bad interaction between very recent R (3.2.2) changes and Rcpp; another related one was also addressed. A big Thanks! to everybody helping with code, bug reports or documentation, See below for a detailed list of changes extracted from the NEWS file.

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.
