R package crossmap by rossellhayes — release notes from GitHub.

github.com/rossellhayes/crossmap ↗

crossmap's roadmap is set by purrr and furrr — it deprecates what upstream deprecates.

purrr extensionfunctional programmingdeprecationsfurrrr package
◆Current state
A small package for mapping over combinations of arguments, following purrr and furrr conventions. Its own functional additions stopped after xpluck() in 2023 and the cross_fit() clustering work in 2022. Everything since tracks upstream: xmap_raw() and future_xmap_raw() are now defunct because purrr removed map_raw() and furrr removed future_pmap_raw(), and re-exported parallel helpers now come from parallelly rather than future.
◆Where it's heading
The package has settled into being a compatible extension rather than an independent one — its release notes read as a mirror of purrr's and furrr's deprecation schedules. Note that the release stamps are unreliable here: several versions were backfilled minutes apart and the 0.3.x tags carry timestamps in reverse version order, so feed position says nothing about what shipped when.
◆Prediction
Expect the next release to be driven by another purrr or furrr change rather than new functionality, since that has been the sole trigger for the last four.

◆Recent moves

  1. 6mo ago

    Raw-vector mapping functions removed

    xmap_raw() and future_xmap_raw() become defunct, completing the removal begun when purrr deprecated its *_raw() family. Callers relying on them break rather than warn — the upstream schedule now sets this package's API.

    Re-exports moved to the parallelly namespace

    Re-exported functions now come from parallelly instead of future. A namespace correction with no behavioural change, published two minutes before 0.5.0.

    Future-backed tests skipped on CRAN

    Skips tests of the future-backed functions on CRAN to avoid check failures. Packaging only.

    Internal test fixes

    Non-user-facing changes to fix test failures, published seconds before 0.4.2. Two halves of one maintenance push.

    xpluck adds multi-index plucking

    Adds xpluck(), a purrr::pluck() variant accepting multiple indices at each step, and deprecates the *_raw() functions in step with purrr 1.0.0. The last release to add capability of its own.

    Cluster specifications supported in cross_fit

    cross_fit() gains a clusters argument for models like estimatr::lm_robust(), with a cross_fit_robust() wrapper, and tidy_glance() moves to broomExtra for wider model coverage. Note the stamp: this tag sits above 0.3.2 and 0.3.3 in the feed despite being the older version.
