kde1d vs roclang
A side-by-side editorial comparison of kde1d and roclang — release velocity, themes, recent moves, and the top alternatives to consider.
Shared themes:r-package
kde1d vs roclang: 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 roclang?
A roxygen2 documentation-reuse helper whose release notes are mostly upstream damage control.
roclang lets package authors pull documentation text out of an existing function's roxygen block and splice it into their own — extract_roc_text() with type = "param", "dot_params" or a section selector. The feature surface has been stable since 0.2.1; the parameter-matching rules and the checks for invalid or ambiguous extractions are the substance of what shipped.

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.
roclang
0.0ANALYTICS
A roxygen2 documentation-reuse helper whose release notes are mostly upstream damage control.
◆ Current state
roclang lets package authors pull documentation text out of an existing function's roxygen block and splice it into their own — extract_roc_text() with type = "param", "dot_params" or a section selector. The feature surface has been stable since 0.2.1; the parameter-matching rules and the checks for invalid or ambiguous extractions are the substance of what shipped.
◆ Where it's heading
Nearly every release since 0.2.0 has been reactive. The package parses documentation text produced by other packages, so a wording change in stats::lm()'s documentation breaks its test suite, and a roxygen2 selection-semantics change forces its parameter matching to follow. The 0.2.3 release is exactly this pattern again. Release cadence has slowed to roughly one entry every two years, and the last two carried no functional change at all.
◆ Prediction
Further releases are most likely triggered by upstream roxygen2 or base R documentation edits breaking tests rather than by new extraction capability. The entries show no queued feature work.

Frequently asked questions
What is the difference between kde1d and roclang?
Both compete on the same themes — r-package — within Analytics. kde1d and roclang 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 roclang?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. kde1d and roclang are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
