cpp4r 0.6.0

CRAN release: 2026-05-17

  • register() now captures the C++ namespace of decorated functions and emits fully-qualified declarations and calls, so functions defined inside a namespace { ... } block (or written as ns::fun) can be registered without further setup.
  • Removed the run-time dependency on the decor, tibble, and vctrs packages; the small subset of helpers that register() relies on is now bundled internally and uses base data.frame.
  • Adds fast paths that provide slight speed improvements (e.g., avoiding branching)
  • Follows, to the best possible extent, the R’s C API description from https://github.com/hadley/r-internals.
  • Slightly expanded cpp4r::function.
  • Fixed two empty tests.

cpp4r 0.4.0

CRAN release: 2025-12-04

  • Clearer documentation about the C++ workflow (i.e., how to use anticonf to specify a C++ standard)
  • Allows for default values like my_fun(int x = 100) to call my_fun() with the same result as my_fun(100L) from R
