kde1d vs nat.templatebrains

kde1d vs nat.templatebrains: 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 nat.templatebrains?
The natverse package that taught neuron data to remember which brain space it lives in.
nat.templatebrains handles registration between template brain spaces — xform_brain(), mirror_brain(), and the bridging-registration graph that finds a path from one template to another. Since 0.8 transformed objects carry a regtemplate attribute recording their space, so downstream natverse functions can usually infer it rather than being told. The package is now in low-cadence maintenance, with 1.2.1 blocked on a CRAN submission window rather than on code.

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.
nat.templatebrains
0.0ANALYTICS
The natverse package that taught neuron data to remember which brain space it lives in.
◆ Current state
nat.templatebrains handles registration between template brain spaces — xform_brain(), mirror_brain(), and the bridging-registration graph that finds a path from one template to another. Since 0.8 transformed objects carry a regtemplate attribute recording their space, so downstream natverse functions can usually infer it rather than being told. The package is now in low-cadence maintenance, with 1.2.1 blocked on a CRAN submission window rather than on code.
◆ Where it's heading
The substantive design work finished years ago. The arc ran from manual space bookkeeping, through memoised bridging-sequence lookup, to self-describing objects at 0.8 — after which releases became dependency hygiene and CRAN paperwork. Two of the last three entries change no code at all: one demotes Morpho from Imports to Suggests, the other updates submission comments.
◆ Prediction
The next release is most likely the delayed 1.2.1 CRAN submission itself. The entries show no pending functional work beyond it.
