kde1d vs NHSRwaitinglist

kde1d vs NHSRwaitinglist: at a glance
What is kde1d?
A univariate density estimator that added zero-inflated data and reopened its C++ API to do it.
kde1d estimates univariate densities with local polynomial kernel methods, handling bounded, discrete and now zero-inflated variables through a single type argument, with the numerical work in a header-only C++ library usable outside R. Version 1.1.0 added the zero-inflated discrete-continuous mixture case and shipped a new C++ API as an explicit breaking change; 1.1.1 followed in June with auto-generated notes and no description.
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.
kde1d vs NHSRwaitinglist: editorial side-by-side
kde1d
0.0ANALYTICS
A univariate density estimator that added zero-inflated data and reopened its C++ API to do it.
◆ Current state
kde1d estimates univariate densities with local polynomial kernel methods, handling bounded, discrete and now zero-inflated variables through a single type argument, with the numerical work in a header-only C++ library usable outside R. Version 1.1.0 added the zero-inflated discrete-continuous mixture case and shipped a new C++ API as an explicit breaking change; 1.1.1 followed in June with auto-generated notes and no description.
◆ Where it's heading
The package has alternated between performance work and widening the class of data it accepts. The 1.0.0 release was the performance milestone — FFT-based estimation, a better integration algorithm for the p, q and r functions, deterministic jittering replacing randomness, and standalone C++ headers. The 1.1.0 release is the scope milestone, adding a third data type to the two it already handled. Releases come from the same maintainer as svines and cluster on shared dates, so changes in the underlying C++ surface across the vine and density stack tend to ship together.
◆ Prediction
With the C++ API deliberately reworked for standalone use at 1.1.0, further work most plausibly consolidates that interface rather than adding data types. What 1.1.1 actually changed is not readable from its body.
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.
