crossmap vs NHSRwaitinglist
A side-by-side editorial comparison of crossmap and NHSRwaitinglist — release velocity, themes, recent moves, and the top alternatives to consider.
crossmap vs NHSRwaitinglist: 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 NHSRwaitinglist?
Queuing theory packaged for NHS waiting-list managers, one year into a community-built first release.
NHSRwaitinglist turns queuing-theory methods into functions an NHS analyst can apply directly to a waiting list — target calculations for managing list size, simulation of list behaviour under different assumptions, and scheduling and prioritisation helpers. It is an NHS-R Community collaboration accompanying a preprint tutorial and webinar series, and reached CRAN in April 2025.

◆ 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.
NHSRwaitinglist
0.0ANALYTICS
Queuing theory packaged for NHS waiting-list managers, one year into a community-built first release.
◆ Current state
NHSRwaitinglist turns queuing-theory methods into functions an NHS analyst can apply directly to a waiting list — target calculations for managing list size, simulation of list behaviour under different assumptions, and scheduling and prioritisation helpers. It is an NHS-R Community collaboration accompanying a preprint tutorial and webinar series, and reached CRAN in April 2025.
◆ Where it's heading
Three releases in four months trace a normal early-package path: ship the method surface, then harmonise arguments and column handling across functions as contributors find the inconsistencies, then repair what breaks. The package was briefly pulled from CRAN over broken links and needed a date-handling fix for newer R versions, which is the sharper edge of that curve. Contributions are visibly multi-author, with named contributors driving the usability work rather than a single maintainer.
◆ Prediction
Given the pattern of contributor-driven consistency fixes and the tutorial paper behind the package, further vignettes and argument harmonisation are the most likely next release. The entries do not indicate new queuing methods being added.

Frequently asked questions
What is the difference between crossmap and NHSRwaitinglist?
They serve adjacent needs but don't currently overlap on shipped themes. crossmap and NHSRwaitinglist 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 NHSRwaitinglist?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. crossmap and NHSRwaitinglist are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
