RcppArmadillo 0.3.910.0

August 15, 2013

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

A new minor release 3.910.0 of Armadillo
came out a few days ago. A new
release 0.3.910.0 was provided rightaway, and after a brief back-and-forth with
CRAN (mostly having to do with the
non-standard vignette corresponding to
our CSDA paper and
its use of LaTeX minted)
is now on CRAN
and also in Debian.

Conrad made some standard cross-products faster, and added
vectorise(), any()
and all() functions. We also added an extension header for more
automated conversion of sparse matrices (which is
already used by a post on the Rcpp Gallery).

The complete list of changes is below.

Changes in RcppArmadillo version 0.3.910.0 (2013-08-12)

  • Upgraded to Armadillo release Version 3.910.0 (Pyrenees)

    • faster multiplication of a matrix with a transpose of
      itself, ie. X*X.t() and X.t()*X

    • added vectorise() for reshaping matrices into vectors

    • added all() and any() for indicating presence
      of elements satisfying a relational condition

  • Added conversion support for sparse matrices (of type double)
    created by the
    package as class dgCMatrix

  • Moved vignette sources from inst/doc to vignettes;
    set BuildVignettes: FALSE as the minted mode for
    LaTeX upsets the CRAN builders.

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
