RcppArmadillo 0.4.320.0

July 12, 2014

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

While I was out at the (immensely impressive and equally enjoyable)
useR! 2014 conference at
Conrad provided a bug-fix release
4.320 of Armadillo, the nifty
templated C++ library for linear algebra. I quickly rolled that into
release 0.4.320.0 which has been on
CRAN and in
Debian for a good week now.

This release fixes some minor things with sparse and dense Eigen solvers (as
well as one RNG issue probably of lesser interest to R users deploying the
RNGs from R) as shown in the NEWS entry below.

Changes in RcppArmadillo version 0.4.320.0 (2014-07-03)

  • Upgraded to Armadillo release Version 4.320 (Daintree Tea Raider)

    • expanded eigs_sym() and eigs_gen() to use an optional tolerance parameter

    • expanded eig_sym() to automatically fall back to standard decomposition method if divide-and-conquer fails

    • automatic installer enables use of C++11 random number generator when using gcc 4.8.3+ in C++11 mode

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.
