crossmap vs fracture
A side-by-side editorial comparison of crossmap and fracture — release velocity, themes, recent moves, and the top alternatives to consider.
crossmap vs fracture: at a glance
What is crossmap?
crossmap's roadmap is set by purrr and furrr — it deprecates what upstream deprecates.
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.
What is fracture?
fracture solved decimal-to-fraction conversion years ago and now only answers to CRAN.
A single-purpose package converting decimals to fractions, with a matrix form and a Unicode pretty-printer. The functional work finished in 2021-2022: an explicit denom argument, named-argument-only calling, sensible denominators at 0 and 1, and NA and Inf handled rather than erroring. The only release since is a four-year-later removal of a C++11 system requirement that R's C++17 default made redundant.

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

0.0ANALYTICS
fracture solved decimal-to-fraction conversion years ago and now only answers to CRAN.
◆ Current state
A single-purpose package converting decimals to fractions, with a matrix form and a Unicode pretty-printer.

The only release since is a four-year-later removal of a C++11 system requirement that R's C++17 default made redundant.
◆ Where it's heading
This is a completed utility. Its arc ran from correctness — floating-point rounding, exhaustive tests across millions of fractions — through API tightening, to edge-case tolerance, and then stopped. The 2026 release contains no user-visible change at all; it exists because CRAN's toolchain moved, which is the characteristic maintenance mode of a small package that does one thing correctly.
◆ Prediction
Nothing in these entries suggests new functionality; expect further releases only when R or CRAN policy forces one, as this one did.

Frequently asked questions
What is the difference between crossmap and fracture?
They serve adjacent needs but don't currently overlap on shipped themes. crossmap and fracture are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is crossmap better than fracture?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. crossmap and fracture are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
