A few days ago Conrad announced the first release candidate of what will become Armadillo 8.500; we wrapped this up as RcppArmadillo 0.8.499.0.2 (with a different version so allow for clean sorting and upgrades).
It contains a number of sparse matric improvements and new features, and Keith O'Hara cleaned up our interfacing with 'limited' LAPACK libraries (such as the one R ships with) improved. This release is ready via GitHub and in the RcppCore drat repo, so please help by testing it. I ran two full reverse-dependency checks and found no issues. You can install from the drat repo at http://rcppcore.github.io/drat/ via a simple drat::addRepo("RcppCore") install.packages("RcppArmadillo") or even just install.packages("RcppArmadillo", type="source", repo="https://RcppCore.github.io/drat") Thanks, Dirk #### Changes in RcppArmadillo version 0.8.499.0.2 (2018-03-29) - Upgraded to Armadillo release 8.500.rc1 (8.500 rc1) - faster element access in sparse matrices - faster row iterators for sparse matrices - faster handling of compound expressions by `trace()` - expanded `normalise()` to handle sparse matrices - expanded `.transform()` and `.for_each()` to handle sparse matrices - added `reverse()` for reversing order of elements - added `roots()` for finding the roots of a polynomial - Fewer LAPACK compile-time guards are used, new unit tests for underlying features have been added (Keith O'Hara in [\#211](https://github.com/RcppCore/RcppArmadillo/pull/211) addressing [\#207](https://github.com/RcppCore/RcppArmadillo/issues/207)). - The configure check for LAPACK features has been updated accordingly (Keith O'Hara in [\#214](https://github.com/RcppCore/RcppArmadillo/pull/214) addressing [\#213](https://github.com/RcppCore/RcppArmadillo/issues/213)). -- http://dirk.eddelbuettel.com | @eddelbuettel | e...@debian.org _______________________________________________ Rcpp-devel mailing list Rcpp-devel@lists.r-forge.r-project.org https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
