Overview

About
Maintained by Michel LangFirst published 2016-02-2024 releasesCRAN page ↗GitHub ↗

Functions introduced or changed since R v3.0.0 are re-implemented in this package. The backports are conditionally exported in order to let R resolve the function name to either the implemented backport, or the respective base version, if available. Package developers can make use of new functions or arguments by selectively importing specific backports to support older installations.
