RApiDatetime 0.0.4: Updates and Extensions

The first update in a little while brings us release 0.0.4 of RApiDatetime which got onto CRAN this morning via the lovely automated sequence of submission, pretest-recheck and pretest-publish.

RApiDatetime provides seven 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. This releases brings asDatePOSIXct as a seventh courtesy of Josh Ulrich. All these functions are all fairly useful, but not one of them was previously exported by R for C-level use by other packages. Which is silly as this is generally extremely carefully written and tested code.

I also updated the exported base R code to what is in R 3.5.1 right now, added a few #nocov declarations (not all which are reflected at the codecov page yet, and added a dependency badge at the GitHub repo.

Changes in RApiDatetime version 0.0.4 (2018-10-21)

  • New function asDatePOSIXct (Josh Ulrich in #2)

  • Synchronized with upstream code in base R (Dirk in #3)

Courtesy of CRANberries, there is a comparison to the previous release. More information is on the rapidatetime page.
