kde1d vs questionr
A side-by-side editorial comparison of kde1d and questionr — release velocity, themes, recent moves, and the top alternatives to consider.
kde1d vs questionr: 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 questionr?
questionr's survey helpers are finished; recent releases only keep pace with R-devel.
A long-running toolkit for survey data in R — proportion tables, weighted counts, and the interactive irec(), iorder() and icut() addins for recoding. The last functional release was 0.8.0 in March 2025: a new freqtable() function, prop(), cprop() and rprop() extended to tables of three or more dimensions, and the addins moved onto the native pipe and forcats' current API. Both releases since exist purely to fix tests broken by R-devel changes to table internals.

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.
questionr
0.0ANALYTICS
questionr's survey helpers are finished; recent releases only keep pace with R-devel.
◆ Current state
A long-running toolkit for survey data in R — proportion tables, weighted counts, and the interactive irec(), iorder() and icut() addins for recoding. The last functional release was 0.8.0 in March 2025: a new freqtable() function, prop(), cprop() and rprop() extended to tables of three or more dimensions, and the addins moved onto the native pipe and forcats' current API. Both releases since exist purely to fix tests broken by R-devel changes to table internals.
◆ Where it's heading
This is a stable package in compatibility-maintenance mode, where the release trigger is upstream churn rather than user demand. The functional work that does appear follows a consistent line — generalising the table functions beyond two dimensions, and keeping the interactive recoding addins aligned with current tidyverse idioms rather than the deprecated ones they were written against. The same maintainer's rainette shipped its own upstream-compatibility fix in the same window.
◆ Prediction
Expect the next release to be another R-devel or tidyverse compatibility fix; nothing in the entries points to new functionality.

Frequently asked questions
What is the difference between kde1d and questionr?
They serve adjacent needs but don't currently overlap on shipped themes. kde1d and questionr 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 kde1d better than questionr?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. kde1d and questionr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
