Rcpp 0.9.11

June 22, 2012

(This article was first published on Thinking inside the box , and kindly contributed to R-bloggers)

Release 0.9.11 of Rcpp
arrived on CRAN this morning and in
Debian later today.

This is a somewhat incremental release with a few internal improvements and
few new features. One interesting new development has been contributed by
John Chambers who is extending ‘Rcpp modules’ into ‘Rcpp classes’ which
allows R code to modify and extend C++ classes loaded via Rcpp modules; see
help(setRcppClass) for more.
This also lead to some changes in the code for loading modules which however
requires the brand-new R version 2.15.1 released today as well.

The complete NEWS entry for 0.9.11 is below; more details are in the ChangeLog file in the package and on the
Rcpp Changelog page.

0.9.11  2012-06-22

    o   New member function for vectors (and lists etc) containsElementNamed() 
        which returns a boolean indicating if the given element name is present

    o   Updated the Rcpp.package.skeleton() support for Rcpp modules by
        carrying functions already present from the corresponding unit test
        which was also slightly expanded; and added more comments to the code 

    o   Rcpp modules can now be loaded via loadRcppModules() from .onLoad(),
        or via loadModule("moduleName") from any R file 

    o   Extended functionality to let R modify C++ clases imported via modules
        documented in help(setRcppClass)

    o   Support compilation in Cygwin thanks to a patch by Dario Buttari

    o   Extensions to the Rcpp-FAQ and the Rcpp-modules vignettes

    o   The minium version of R is now 2.15.1 which is required for some of
        the Rcpp modules support 

Thanks to
CRANberries, you can also look at a
diff to the previous release 0.9.10.
As always, even fuller details are on the
Rcpp Changelog page and the
Rcpp page which also
leads to the downloads, the
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
