A small Armadillo bugfix upstream update 9.800.3 came out a few days ago. The changes, summarised by Conrad in email to me (and for once not yet on the arma site are fixes for matrix row iterators, better detection of non-hermitian matrices by eig_sym(), inv_sympd(), chol(), expmat_sym() and miscellaneous minor fixes. It also contains a bug fix by Christian Gunning to his sample() implementation.

Armadillo is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 679 other packages on CRAN.

Changes in RcppArmadillo version 0.9.800.3.0 (2019-12-04)

  • Upgraded to Armadillo release 9.800.3 (Horizon Scraper)

  • The sample function passes the prob vector as const allowing subsequent calls (Christian Gunning in #276 fixing #275)

Courtesy of CRANberries, there is a diffstat report relative to previous release. More detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.
