Rcpp 0.9.8 went to CRAN this morning, below is the usual blog post in case
you haven't seen it (and the blog at http://dirk.eddelbuettel.com/blog/ has
A new release 0.9.8 of Rcpp is now on CRAN and will also get into Debian
shortly (once I finish building R 2.14.1).
This release contains a few incremental changes. Romain, sponsored by by
the Open Source Programs Office at Google, had released a new package
int64 bringing larger integers to R, and this is now supported by Rcpp as
well. John Chambers contributed some code to have Reference Classes extend
existing C++ classes (typically brought in via Rcpp Modules). Jelmer Ypma
sent us a patch to add a Rcout device not unlike cout, but aligned with
R's io buffering. We added some more unit tests, and made a few small
fixes here or there.
The complete NEWS entry is below; more details are in the ChangeLog file
in the package and on the Rcpp Changelog page.
o wrap now handles 64 bit integers (int64_t, uint64_t) and containers
of them, and Rcpp now depends on the int64 package (also on
CRAN). This work has been sponsored by the Google Open Source
o Added setRcppClass() function to create extended reference classes
with an interface to a C++ class (typically via Rcpp Module) which
can have R-based fields and methods in addition to those from the C++.
o Applied patch by Jelmer Ypma which adds an output stream class
'Rcout' not unlike std::cout, but implemented via Rprintf to
cooperate with R and its output buffering.
o New unit tests for pf(), pnf(), pchisq(), pnchisq() and pcauchy()
o XPtr constructor now checks for corresponding type in SEXP
o Updated vignettes for use with updated highlight package
o Update linking command for older fastLm() example using external
Thanks to CRANberries, you can also look at a diff to the previous release
0.9.7. As always, even fuller details are on the Rcpp Changelog page and the
Rcpp page which also leads to the downloads, the browseable doxygen docs and
zip files of doxygen output for the standard formats. A local directory has
source and documentation too. Questions, comments etc should go to the
rcpp-devel mailing list off the R-Forge page
