A distribution catalogue that grows by one family at a time, and rarely breaks anything.
A side-by-side editorial comparison of ecotraj and randomwalk — release velocity, themes, recent moves, and the top alternatives to consider.
Ecological trajectory analysis builds out its cyclical branch, largely through one contributor
ecotraj analyses ecological community trajectories through multivariate space, and since 1.0.0 has carried cyclical ecological trajectory analysis (CETA) alongside the linear methods. Recent releases add convergence plotting, cycle shift arrows, correspondence and reduced major axis functions, and now trajectory averaging — most credited to a single contributor, N. Djeghri. Several older release notes are bare pointers to NEWS rather than descriptions.
randomwalk spent every release getting an R simulation to run in the browser, not on a server.
A random walk and fractal-growth simulation package whose entire visible history is about its browser deployment. Six releases in four weeks moved a Shinylive dashboard from a blank black page to a working app — WebAssembly mounted from GitHub releases, CORS resolved by same-origin serving, missing plotting dependencies installed in-browser, then an async version using crew workers with its own debug log. A correctness fix followed, adding termination-position validation so simulations stop producing isolated pixels, and the most recent release publishes the package itself as a webR binary repository.

The centre of gravity has shifted to cycles. The 1.0.0 release introduced CETA and reworked the underlying data structures for it, and every release since extends the cyclical branch or teaches an existing function to handle cycle objects — trajectoryDistances now compares cycles using dates for time comparison, and averageTrajectories covers both trajectories and cycles. A dependency on the MannKendall package was dropped in favour of base cor.test, trimming the install footprint.
The pattern of teaching existing linear-trajectory functions to accept cycle objects has repeated across several releases, so further functions gaining cycle support is the most grounded expectation.

The package is being built as a browser artifact first and an R package second: the readme, the vignettes and the release notes all point at a hosted dashboard rather than at library(). The last release completes that by making the compiled WebAssembly build installable by anyone via webr::install(), which turns the deployment work into something reusable outside this project. Version numbers are unreliable here — v0.2.0 was published two weeks after v1.0.2 — so read the dates, not the tags.
With the webR repository published, the next work most likely moves back to the simulation itself, though the entries give no direct evidence of planned features.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. ecotraj and randomwalk 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.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. ecotraj and randomwalk are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
