RcppArmadillo 0.7.700.0.0

Time for another update of RcppArmadillo with a new release 0.7.700.0.0 based on a fresh Armadillo 7.700.0. Following my full reverse-dependency check of 318 package (commit of log here), CRAN took another day to check again.

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) 318 other packages on CRAN -- an increase of 20 just since the last CRAN release of 0.7.600.1.0 in December!

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

Changes in RcppArmadillo version 0.7.700.0.0 (2017-02-07)

• Upgraded to Armadillo release 7.700.0 ("Rogue State")

  • added polyfit() and polyval()

  • added second form of log_det() to directly return the result as a complex number

  • added range() to statistics functions

  • expanded trimatu()/trimatl() and symmatu()/symmatl() to handle sparse matrice

Changes in RcppArmadillo version 0.7.600.2.0 (2017-01-05)

• Upgraded to Armadillo release 7.600.2 (Coup d'Etat Deluxe)

  • Bug fix to memory allocation for fields

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.
