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
