A first minor bug-fix update by Conrad to the 3.6 series of
Armadillo arrived today as
version 3.6.1, and we prepared a corresponding version of
our wrapper for
R and Armadillo.
This is now on
CRAN, and the changes are summarized below.

Changes in RcppArmadillo version (2012-12-17)

  • Upgraded to Armadillo release Version 3.6.1

    • faster trace()

    • fix for handling sparse matrices by dot()

    • fixes for interactions between sparse and dense matrices

  • Now throws compiler error if Rcpp.h is included before
    RcppArmadillo.h (as the former is included automatically by the
    latter anyway, but template logic prefers this ordering).

Courtesy of
CRANberries, there
is also a diffstat report for the
most recent release
As always, more detailed information is on the
RcppArmadillo page.
Questions, comments etc should go to the
rcpp-devel mailing list
off the R-Forge page.
