A new version of RcppGSL arrived on CRAN a couple of days ago. This package provides an interface from R to the GNU GSL using our Rcpp package.

In the course of preparation for the higher-performance R via C++ course I gave in Zuerich last month, I overhauled this package, its embedded package (!!) showing how to build a package which uses R, C++ and the GSL (and which can serve as a fine example of how to build and R and C++ package using an external library), and also overhauled the vignette which discusses all these aspect. All examples now consistently use Rcpp Attributes.

The NEWS file entries follows below:

Changes in version 0.2.5 (2015-07-05)

• The colnorm function in the included example package was rewritten to use Rcpp Attributes, the example package was updated and its version number increased to 0.0.3.

• The unit tests also use the updated version of the example package.

• The package, and the included example package, were updated throughout to conform to the current R CMD check standards.

• The RcppGSL-intro vignette was updated throughout.

• The Travis CI integration now uses r-cran-* packages which leads to faster tests.

Courtesy of CRANberries, a summary of changes to the most recent release is available.

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