RInside 0.2.5 arrived on CRAN earlier today. RInside is a set of convenience classes which facilitate embedding of R inside of C++ applications and programs, using the classes and functions provided by the Rcpp R and C++ integration package.

The big news for this release is that Windows applications once again run! James Bates gets full credit for noticing why Windows binaries died on startup, and provided a short patch which we (after some further simplicifcation) added. So for the first time since the 0.2.0 release, Windows users can just change into the examples/standard directory and issue a simple make -f Makefile.win, and the twelve example binaries will actually work. Yay, and kudos to James.

The other main addition is a new examples directory examples/wt containing the web-application of the density estimation demo I had blogged about last week. By combining the Wt toolkit with RInside, we get C++ “web” applications containing R which is pretty nifty. The example otherwise follows the earlier Qt-based example of a standard desktop application with RInside.

One minor snafu I just noticed is that I was overzealous with the .Rbuildignore file. By excluding the wt and qtbinaries, I also excluded their source files with the same name (up to the .cpp or .h ending). If you desire to run the examples, just grab these examples files from the SVN repo at R-Forge.

All changes since the last release are summarized below: 

0.2.5   2011-12-07

   o    Applied (somewhat simplified) patch by James Bates which restores
        RInside to working on Windows -- with a big Thank You! to James for
        fixing a long-standing bug we inadvertendly introduced right after
        0.2.0 almost two years ago

   o    New example embedding R inside a Wt (aka Webtoolkit, pronounced 
        'witty') application, mirroring the previous Qt application

   o    Qt example qtdensity now uses the new svg() device in base R; removed
        test for cairoDevice package as well as fallback png code

   o    Very minor fix to qmake.pro file for Qt app correcting link order
CRANberries also provides a short report with changes from the previous release. More information is on the RInside page. Questions, comments etc should go to the rcpp-devel mailing list off the Rcpp R-Forge page.
