RcppGSL 0.2.1 and 0.2.2

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

A few days ago, version 0.2.1 of RcppGSL---our interface package between R and the GNU GSL using our Rcpp package for seamless R and C++ integration---appeared on CRAN making it the first release in some time.

And it turned that this version tickled an obscure and long-dormant bug under clang which was found on OS X Mavericks---which Kevin Ushey consequently squashed. So this is now reflected in version 0.2.2 which just arrived on CRAN.

Besides the bugfix, a few things were modernized to reflect capabilities of Rcpp 0.11.0 and later. The releases also contain a few changes that had accumulated since the previous release in 2012 such as an additional example using B-splines, and use of updated vignette build options provided by R.

The NEWS file entries follows below:

Changes in version 0.2.2 (2014-05-31)

  • A subtle bug (tickled only by clang on some OS versions) in vector and matrix view initialization was corrected by Kevin Ushey

Changes in version 0.2.1 (2014-05-26)

  • Added new example based on B-splines example in GSL manual illustrating simple GSL use via Rcpp attributes

  • Vignette compilation has been reverted to using highlight since version 0.4.2 or greater can be used as a vignette engine (with R 3.0.* or later).

  • Vignette compilation is now being done by R CMD build as R 3.0.0 supports different vignette engines, so the vignette build process has been simplified. A convenience helper script has also been added for command-line builds.

  • Unit tests now use sourceCpp() instead of cxxfunction() from the inline package

  • The DESCRIPTION file now uses Suggests: Rcpp (instead of Depends: Rcpp) to permit building of the vignette

  • The package now takes advantage of the simplified build process available with Rcpp (>= 0.11.0)

  • Similar updates to the build process were made for the example package included with RcppGSL

And courtesy of CRANberries, a summaries of changes to release 0.2.0 and this week's release 0.2.1 are available.

More information is on the RcppGSL page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.
