Rcpp 0.9.15
Rcpp release 0.9.15 is now on CRAN and being uploaded to Debian. Martin Morgan provided a clever fix for a header search needed between clang++ (especially on OS X) and g++ (which still provided libstdc++ and headers for clang++). This should hopefully put the clang issues to bed. Ben North noticed an unprotected string conversion when exception...

Accelerating R code: Computing Implied Volatilities Orders of Magnitude Faster
This blog, together with Romain’s, is one of the main homes of stories about how Rcpp can help with getting code to run faster in the context of the R system for statistical programming and analysis. By making it easier to get already existing C or C++ code to R, or equally to extend R with new C++ code, Rcpp can help in getting stuff done. An...

Rcpp and the new R:: namespace for Rmath.h
We released Rcpp 0.10.0 earlier today. This post will just provide a simple example for one of the smaller new features — the new namespace for functions from Rmath.h — and illustrate one of the key features (Rcpp attributes) in passing. R, as a statistical language and environment, has very well written and tested statistical distribution ...

Rcpp attributes: A simple example ‘making pi’
We introduced Rcpp 0.10.0 with a number of very nice new features a few days ago, and the activity on the rcpp-devel mailing list has been pretty responsive which is awesome. But because few things beat a nice example, this post tries to build some more excitement. We will illustrate how Rcpp attributes makes it really easy to add C++ code to R ...

digest 0.6.0
A new version of the digest package (which generates hash function summaries for arbitrary (and possibly nested) R objects using any of the standard md5, sha-1, sha-256, sha-512 or crc32 algorithms) is now on CRAN, and I will push the corresponding version into Debian in a moment. For this release, Hannes Muehleisen added support for sha-512 usi...
