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)
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.
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 buildas 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
cxxfunction()from the inline package
DESCRIPTIONfile 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
