R API for 'Date' and 'Datetime'

Access to the C-level R date and 'datetime' code is provided for C-level API use by other packages via registration of native functions. Client packages simply include a single header 'RApiDatetime.h' provided by this package, and also 'import' it. The R Core group is the original author of the code made available with slight modifications by this package.

RApiDatetime: R Date and Datetime Functionality at the C Level

About

This package provides C-level date / datetime functionality taken from the R sources and made available for use by other packages.

It is useful if you are writing C (or C++) code in an R package which needs to parse, format or transform date(time) objects, and want to do this at the compiled level, i.e. faster than calling back to the corresponding R level function could do it.

Installation

The package is now on CRAN and can be installed via a standard

install.packages("RApiDatetime")

Copyrights

Copyrights are held by the respective authors, in particular the R Core Team for the included code from R, and Dirk Eddelbuettel for any modificatons, integration and the remainder of the package.
