News for Package RcppZiggurat

Changes in version 0.1.6 (2020-10-18)

• Several typos were corrected in the vignette (Blagoje Ivanovic in #9).

• New getters and setters for internal state were added to resume simulations (Dirk in #11 fixing #10).

• Minor updates to cleanup script and Travis CI setup (Dirk).

Changes in version 0.1.5 (2018-06-10)

• Description rewritten using doi for references.

• Re-setting the Ziggurat generator seed now correctly re-sets state (Ralf Stubner in #7 fixing #3)

• Dynamic registration reverts to manual mode so that user_norm_rand() is visible as well (#7).

• The vignette was updated to accomodate pandoc 2* [CRAN request].

Changes in version 0.1.4 (2017-09-27)

• The vignette now uses the pinp package in two-column mode.

• Dynamic symbol registration is now enabled.

Changes in version 0.1.3 (2015-07-25)

• Use the SHR3 generator for the default implementation just like Leong et al do, making our default implementation identical to theirs (but 32- and 64-bit compatible)

• Switched generators from float to double ensuring that results are identical on 32- and 64-bit platforms

• Simplified builds with respect to GSL use via the RcppGSL package; added a seed setter for the GSL variant

• Corrected use of fabs() to abs() on integer variables, with a grateful nod to Brian Ripley for the hint (based on CRAN checks on the beloved Slowlaris machines)

• Accelerated Travis CI tests by relying exclusively on r-cran-* packages from the PPAs by Michael Rutter and myself

• Updated DESCRIPTION and NAMESPACE according to current best practices, and R-devel CMD check --as-cran checks

Changes in version 0.1.2 (2013-12-28)

• Add a new generator deploying R's unif_rand which faciliates use of Ziggurat as the user-supplied generator for N(0,1)

• Update a 'local' demo comparing normal distribution RNGs from Boost, C++11 and Armadillo none of which are particularly speedy

• Add declaration to import a symbol from Rcpp to NAMESPACE to ensure proper instantiation with the upcoming Rcpp version

Changes in version 0.1.1 (2013-12-22)

• Set dependency on R (>= 3.0.0) needed by vignette builder

• Remove pdf files in vignette on cleanup to ensure rebuilds

Changes in version 0.1.0 (2013-12-21)

• Testing framework added with a standard RNG test, a new and similar test particular for Normal distributions, and the Chi^2 test from the Leong et al paper (JSS, 2005)

• New demo() functionality showing the three added tests.

• Code has been reorganized into separate headers implementing the generators, using a common (virtual) base class; and accessors and tests in the src/ directory.

• Two new ziggurat generators implementations have been adapted from, respectively, GNU Gretl and QuantLib

• Added a vignette

Changes in version 0.0.1 (2013-10-06)

• Initial basic package version, wrapping five different implementations
