RcppArmadillo 0.3.900.7

August 4, 2013

(This article was first published on Thinking inside the box , and kindly contributed to R-bloggers)

A bug-fix release 3.900.7 of Armadillo
was provided by Conrad a few days ago. It has been rolled into a new
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
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

is also a diffstat report for the
