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 RcppArmadillo, 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.
