A bug-fix release 3.900.7 of Armadillo was provided by Conrad a few days ago. It has been rolled into a new RcppArmadillo release 0.3.900.7 which, after a brief delay, is now on CRAN and in Debian.

The main bug fix is a change in the in-place version of reshape(). This in turn caused the CRAN package Amelia to fail, but some diligent debugging by Conrad (which was much appreciated) revealed that the error was in fact in RcppArmadillo where we did not set the matrix flag properly in the constructor. The corresponding one-character fix had been made in this release.

Another package exhibiting an issue is unmarked. It needs to make the target variable of reshape a matrix object in a handful of places. I sent the authors a small patch addressing this but have not yet heard back.

The complete list of changes is below. In the meantime, I have also done some work on a new as() and wrap() converters for sparse matrices; a first implementation is in SVN.

Changes in RcppArmadillo version 0.3.900.7 (2013-08-02)

  • Upgraded to Armadillo release Version 3.900.7 (Bavarian Sunflower)

    • minor fix for inplace reshape()

    • minor corrections for compilation issues under GCC 4.8+ and MSVC

  • Corrected setting of vec_stats in intialization of row, vector and matrix objects

  • The inline package is no longer used in the examples and unit tests which have all been converted to using Rcpp attributes

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.
