RApiDatetime 0.0.11 on CRAN: Micro-Maintenance

Mon, 19 Jan 2026 18:21:00 CDT

A new (micro) maintenance release of our RApiDatetime package is now on CRAN, coming only a good week after the 0.0.10 release which itself had a two year gap to its predecessor release.

RApiDatetime provides a number of entry points for C-level functions of the R API for Date and Datetime calculations. The functions asPOSIXlt and asPOSIXct convert between long and compact datetime representation, formatPOSIXlt and Rstrptime convert to and from character strings, and POSIXlt2D and D2POSIXlt convert between Date and POSIXlt datetime. Lastly, asDatePOSIXct converts to a date type. All these functions are rather useful, but were not previously exported by R for C-level use by other packages. Which this package aims to change.

This release adds a single (and ) around one variable as the rchk container and service by Tomas now flagged this. Which is … somewhat peculiar, as this is old code also ‘borrowed’ from R itself but no point arguing so I just added this.

Details of the release follow based on the NEWS file.

Changes in RApiDatetime version 0.0.11 (2026-01-19)

Add PROTECT (and UNPROTECT) to appease rchk

Courtesy of my CRANberries, there is also a diffstat report for this release.
