RcppArmadillo 0.7.600.1.0

Earlier this week, Conrad released Armadillo 7.600.1. The corresponding RcppArmadillo release 0.7.600.1.0 is now on CRAN and in Debian. This follows several of rounds testing at our end with a full reverse-dependency of a pre-release version followed by another full reverse-depency check. Which was of course followed by CRAN testing for two more days.

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) 298 other packages on CRAN — an increase of 24 just since the last CRAN release of 0.7.500.0.0 in October!

Changes in this release relative to the previous CRAN release 0.7.500.0.0 are as follows:

Changes in RcppArmadillo version 0.7.600.1.0 (2016-12-16)

• Upgraded to Armadillo release 7.600.1 (Coup d’Etat Deluxe)

  • more accurate eigs_sym() and eigs_gen()

  • expanded floor(), ceil(), round(), trunc(), sign() to handle sparse matrices

  • added arg(), atan2(), hypot()

Changes in RcppArmadillo version 0.7.500.1.0 (2016-11-11)

• Upgraded to Armadillo release 7.500.1

• Small improvement to return value treatment

• The sample.h extension was updated to the newer Armadillo interface. (Closes #111)

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