RcppArmadillo 0.10.2.2.0 on CRAN: New Upstream Patch Release

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) 841 other packages on CRAN.

This release brings us a second update within the Armadillo 10.2 series, one month after the initial release. Upstream work has commenced at a 10.3 series with first pre-releases which we are currently testing. If possible, CRAN release will continue to be at least one month apart (such as this time) but we continue to make interim releases available on the Rcpp drat repo repo.

The full set of changes follows.

Changes in RcppArmadillo version 0.10.2.2.0 (2021-03-09)

• Upgraded to Armadillo release 10.2.2 (Cicada Swarm)

  • faster handling of subcubes

  • added tgamma()

  • added .brief_print() for abridged printing of matrices & cubes

  • expanded forms of trimatu() and trimatl() with diagonal specification to handle sparse matrices

  • expanded eigs_sym() and eigs_gen() with optional shift-invert mode

• Removed debian/ directory from repository as packaging is on salsa.debian.org.

• Relaxed tolerance on two cube tests on Windows to accomodate new 'gcc10-UCRT' builder.

Courtesy of my 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.
