aqp vs RandomWalker: at a glance
What is aqp?
The 1.x line, tagged retroactively after a decade of SoilProfileCollection redesign.
aqp provides the SoilProfileCollection class and the algorithms built on it for soil profile data, colour, and taxonomy. The most recent tag in this feed is explicitly retroactive: 1.42 was cut in 2025 to mark the last CRAN state before the 2.0 release. Between 2018 and 2021 the class internals were reworked twice, the Munsell colour tooling grew substantially, and data.table replaced reshape underneath the wide-to-long transformations.
What is RandomWalker?
A random-walk generator that outgrew one dimension and renamed its core column to prove it.
RandomWalker generates families of stochastic paths — Brownian motion, geometric Brownian motion, drift walks, discrete walks — as tidy tibbles, with cumulative-statistic augmenters, summarisers and a visualize_walks() plotting layer on top. The development series before 1.0.0 extended generation to two and three dimensions and renamed the step index from x to step_number, which is the shape the package now carries into its stable release.

aqp
0.0ANALYTICS
The 1.x line, tagged retroactively after a decade of SoilProfileCollection redesign.
◆ Current state
aqp provides the SoilProfileCollection class and the algorithms built on it for soil profile data, colour, and taxonomy. The most recent tag in this feed is explicitly retroactive: 1.42 was cut in 2025 to mark the last CRAN state before the 2.0 release. Between 2018 and 2021 the class internals were reworked twice, the Munsell colour tooling grew substantially, and data.table replaced reshape underneath the wide-to-long transformations.
◆ Where it's heading
Two threads run through the window. The core object was progressively rebuilt - a new horizon-ID slot in 1.17, then a wave of renames and argument removals in 1.25 that broke code deliberately ahead of 2.0. Alongside it, colour work compounded: mixMunsell, spectral mixing, colour quantiles, a chip-frequency chart, and PMS conversion. Tag order here is not release order, since 1.42 was applied to an older commit.
◆ Prediction
This feed reads as a closed chapter - further entries on it would be backfill, with active work having moved to the 2.x series.
RandomWalker
0.0ANALYTICS
A random-walk generator that outgrew one dimension and renamed its core column to prove it.
◆ Current state
RandomWalker generates families of stochastic paths — Brownian motion, geometric Brownian motion, drift walks, discrete walks — as tidy tibbles, with cumulative-statistic augmenters, summarisers and a visualize_walks() plotting layer on top. The development series before 1.0.0 extended generation to two and three dimensions and renamed the step index from x to step_number, which is the shape the package now carries into its stable release.
◆ Where it's heading
The package built outward in clear stages: generators first, then a set of std_cum_*_augment() transformations over the results, then the dimensional generalisation that forced the column rename. That progression suggests a design settling on walks as a tidy data structure to be transformed and plotted rather than a set of one-off simulators. The 1.0.0 tag itself carries no release notes in this feed — its body is stray YAML front matter — so the milestone's own contents cannot be read here.
◆ Prediction
With dimensions generalised and a 1.0.0 cut, further work most plausibly extends the augmenter and summariser layer to multi-dimensional walks. The empty 1.0.0 body means any specific claim about what the stable release contains would be guesswork.
