Rcpp 0.12.13: Updated vignettes, and more

The thirteenth release in the 0.12.* series of Rcpp landed on CRAN this morning, following a little delay because Uwe Ligges was traveling and whatnot. We had announced its availability to the mailing list late last week. As usual, a rather substantial amount of testing effort went into this release so you should not expect any surprise.

This release follows the 0.12.0 release from July 2016, the 0.12.1 release in September 2016, the 0.12.2 release in November 2016, the 0.12.3 release in January 2017, the 0.12.4 release in March 2016, the 0.12.5 release in May 2016, the 0.12.6 release in July 2016, the 0.12.7 release in September 2016, the 0.12.8 release in November 2016, the 0.12.9 release in January 2017, the 0.12.10.release in March 2017, the 0.12.11.release in May 2017, and the 0.12.12 release in July 2017 making it the seventeeth release at the steady and predictable bi-montly release frequency.

Rcpp has become the most popular way of enhancing GNU R with C or C++ code. As of today, 1069 packages (and hence 73 more since the last release) on CRAN depend on Rcpp for making analytical code go faster and further, along with another 91 in BioConductor.

This releases contains a large-ish update to the documentation as all vignettes (apart from the unit test one, which is a one-off) now use Markdown and the (still pretty new) pinp package by James and myself. There is also a new vignette corresponding to the PeerJ preprint James and I produced as an updated and current Introduction to Rcpp replacing the older JSS piece (which is still included as a vignette too).

A few other things got fixed: Dan is working on const iterators you would expect with modern C++, Lei Yu spotted error in Modules, and more. See below for details.

Changes in Rcpp version 0.12.13 (2017-09-24)

  • Changes in Rcpp API:

    • New const iterators functions cbegin() and cend() have been added to several vector and matrix classes (Dan Dillon and James Balamuta in #748) starting to address #741).

  • Changes in Rcpp Modules:

    • Misplacement of one parenthesis in macro LOAD_RCPP_MODULE was corrected (Lei Yu in #737)

  • Changes in Rcpp Documentation:

    • Rewrote the macOS sections to depend on official documentation due to large changes in the macOS toolchain. (James Balamuta in #742 addressing issue #682).

    • Added a new vignette ‘Rcpp-introduction’ based on new PeerJ preprint, renamed existing introduction to ‘Rcpp-jss-2011’.

    • Transitioned all vignettes to the 'pinp' RMarkdown template (James Balamuta and Dirk Eddelbuettel in #755 addressing issue #604).

    • Added an entry on running 'compileAttributes()' twice to the Rcpp-FAQ (##745).

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.
