RcppArmadillo 0.5.600.2.0

And yet another upstream Armadillo update -- version 5.600.2 was released yesterday by Conrad. So I pushed a new and matching RcppArmadillo release 0.5.600.2.0 to CRAN and to Debian.

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.

This release contains small upstream improvements:

Changes in RcppArmadillo version 0.5.600.2.0 (2015-09-19)

• Upgraded to Armadillo 5.600.2 ("Molotov Cocktail Deluxe")

  • expanded .each_col() and .each_row() to handle out-of-place operations

  • added .each_slice() for repeated matrix operations on each slice of a cube

  • faster handling of compound expressions by join_rows() and join_cols()

Courtesy of CRANberries, there is also a diffstat report for the most recent CRAN release. As always, more detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.

RQuantLib 0.4.1

Right before heading off to last week's excellent EARL 2015 conference in London, a new minor release of RQuantLib was released onto CRAN and into Debian.

The changes are detailed below.

Changes in RQuantLib version 0.4.1 (2015-09-11)

• Changes in RQuantLib code:

  • A simple shiny application is now included in the directory shiny/DiscountCurve/ and accessible via the new demo function ShinyDiscountCurve.

  • The option surface plotting example in arrays.R now checks for rgl by using requireNamespace.

  • The files NAMESPACE and DESCRIPTION have been updated to reflect all the suggestions of R CMD check.

  • The Travis CI tests now use binary Debian packages for all package dependencies making the tests a little faster.

Courtesy of CRANberries, there is also a diffstat report for the this release. As always, more detailed information is on the RQuantLib page. Questions, comments etc should go to the rquantlib-devel mailing list off the R-Forge page. Issue tickets can be filed at the GitHub repo.
