Rcpp 0.8.8

A bug-fix release 0.8.8 of Rcpp is now available. It is awaiting processing at CRAN, and will be uploaded to Debian once processed at CRAN. In the meantime, sources are available from my local directory here.

This release follows on the heels of 0.8.7, but contains fixes for a few small things Romain and I had noticed over the last two weeks since releasing 0.8.7 and contains only a small number of new tweaks. The NEWS entry follows below:

0.8.8   2010-11-01

    o   New syntactic shortcut to extract rows and columns of a Matrix. 
        x(i,_) extracts the i-th row and x(_,i) extracts the i-th column. 
    o   Matrix indexing is more efficient. However, faster indexing is
        disabled if g++ 4.5.0 or later is used.

    o   A few new Rcpp operators such as cumsum, operator=(sugar)

    o   Variety of bug fixes:

        - column indexing was incorrect in some cases

        - compilation using clang/llvm (thanks to Karl Millar for the patch)

        - instantation order of Module corrected

        - POSIXct, POSIXt now correctly ordered for R 2.12.0 

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
