A minor maintenance release of the RcppCNPy package arrived on CRAN three days ago, but we skipped announcing it right then.

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.

One of the vignettes created an issue at CRAN with one of the Python modules used, so we simply switched to pre-made vignettes just as we do for a few other packages. Other small changes that had accumulated since the previous release were a new section in the reticulate vignette as well as some more documentation on types as well as some updates to continuous integration and bdages.

Changes in version 0.2.11 (2022-03-24)

• The reticulate vignette has new section on 3d-arrays.

• Added clarification to the manual page that the default types are 32-bit integer and 64-bit double (as we are working with R here).

• Several updates have been made to the CI system; it now runs r-ci.

• The README.md was updated with some new badges.

• The vignettes are now pre-made to avoid any external dependencies.

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.
