RcppSMC 0.2.9 on CRAN: Maintenance

Tue, 09 Sep 2025 15:42:00 CDT

Release 0.2.9 of our RcppSMC package arrived at CRAN today. RcppSMC provides Rcpp-based bindings to R for the Sequential Monte Carlo Template Classes (SMCTC) by Adam Johansen described in his JSS article. Sequential Monte Carlo is also referred to as Particle Filter in some contexts. The package now also features the Google Summer of Code work by Leah South in 2017, and by Ilya Zarubin in 2021.

This release is again entirely internal. It updates the code for the just-released RcppArmadillo 15.0.2-1, in particular opts into Armadillo 15.0.2. And it makes one small tweak to the continuous integration setup switching to the r-ci action.

The release is summarized below.

Changes in RcppSMC version 0.2.9 (2025-09-09)

Adjust to RcppArmadillo 15.0.* by setting ARMA_USE_CURRENT and updating two expressions from deprecated code

Rely on r-ci GitHub Action which includes the bootstrap step

Courtesy of my CRANberries, there is also a diffstat report detailing changes. More information is on the RcppSMC page and the repo. Issues and bugreports should go to the GitHub issue tracker.
