RcppCNPy 0.2.15 on CRAN: Maintenance

Fri, 13 Mar 2026 14:10:00 CDT

Another maintenance release of the RcppCNPy package arrived on CRAN today, and has already been built as an r2u binary. RcppCNPy provides R with read and write access to NumPy files thanks to the cnpy library by Carl Rogers along with Rcpp for the glue to R.

The changes are minor and similar to other recent changes. We aid Rcpp in the transition away from calling Rf_error() by relying in Rcpp::stop() which has better behaviour and unwinding when errors or exceptions are encountered. So once again no user-facing changes. Full details are below.

Changes in version 0.2.15 (2026-03-13)

Replaced Rf_error with Rcpp::stop in three files

Maintenance updates to continuous integration

CRANberries also provides a diffstat report for the latest release. As always, feedback is welcome and the best place to start a discussion may be the GitHub issue tickets page.
