RcppGSL 0.1.0

December 1, 2010

(This article was first published on Romain Francois, Professional R Enthusiast, and kindly contributed to R-bloggers)


We released the first version of our RcppGSL package. RcppGSL extends Rcpp to help programmers code with the GNU Scientific Library (GSL).

The package contains template classes in the RcppGSL namespace that act as smart pointers to the associated GSL data structure. For example, a RcppGSL::vector&lt:double> object acts a smart pointer to a gsl_vector*. Having the pointer shadowed by a smart pointer allows us to take advantage of C++ features such as operator overloading, etc … which for example allows us to extract an element from the GSL vector simply using [] instead of GSL functions gsl_vector_get and gsl_vector_set

The package contains a 11 pages vignette that explains the features in details, with examples. The vignette also discusses how to actually use RcppGSL, either in another package (preferred) or directly from the R prompt through the inline package.
