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.
