fossilsim vs ss3diags
A side-by-side editorial comparison of fossilsim and ss3diags — release velocity, themes, recent moves, and the top alternatives to consider.

fossilsim vs ss3diags: at a glance
What is fossilsim?
A fossil-record simulator that quietly grew a trait-evolution engine.
FossilSim is a mature R package for simulating fossil records on phylogenetic trees, and its release cadence reflects that: long gaps punctuated by a single capability addition. The last four releases span three years, with the most recent being a compatibility sync to its companion Shiny front-end rather than new functionality. The core simulation surface has been stable since 2022.
What is ss3diags?
A fisheries diagnostics package that lives and dies by one upstream dependency.
ss3diags provides residual, retrospective and hindcast cross-validation diagnostics for Stock Synthesis models, sitting directly on top of r4ss. Its recent history is dominated by that dependency: when r4ss 1.50.0 renamed columns across its read and write functions, ss3diags pinned itself to 1.49.3 only, then spent the following release adapting. It now requires r4ss 1.50.0 and above and has moved to native R pipes.

◆ Current state
FossilSim is a mature R package for simulating fossil records on phylogenetic trees, and its release cadence reflects that: long gaps punctuated by a single capability addition. The last four releases span three years, with the most recent being a compatibility sync to its companion Shiny front-end rather than new functionality. The core simulation surface has been stable since 2022.
◆ Where it's heading
The arc runs from sampling mechanics toward simulating what the organisms actually were. Version 2.2.0 taught the package to handle occurrence data for occurrence birth-death models; 2.3.0 then added trait simulation under Mk, BM and OU, which is a different kind of output than fossil ages. Since then the work has been maintenance and keeping the FossilSimShiny GUI in step, suggesting the authors consider the current model set feature-complete.
◆ Prediction
The pairing of the 2.3.3 release with a FossilSimShiny version bump points to the GUI, not the library, as where the next visible work lands. The entries do not show enough activity to predict a specific new model family.
ss3diags
0.0ANALYTICS
A fisheries diagnostics package that lives and dies by one upstream dependency.
◆ Current state
ss3diags provides residual, retrospective and hindcast cross-validation diagnostics for Stock Synthesis models, sitting directly on top of r4ss. Its recent history is dominated by that dependency: when r4ss 1.50.0 renamed columns across its read and write functions, ss3diags pinned itself to 1.49.3 only, then spent the following release adapting. It now requires r4ss 1.50.0 and above and has moved to native R pipes.
◆ Where it's heading
The package is a downstream consumer whose release schedule is largely dictated by NOAA's r4ss. Between compatibility passes it has been shifting documentation from loose cookbook scripts into proper vignettes and shedding bundled Rdata in favour of objects generated at build time. Note that 2.0.3 and 2.1.0 were published the same day, so version order in this feed does not track chronology.
◆ Prediction
The next release most likely follows the next breaking r4ss change; between those, expect continued vignette and parameter-validation work.

Frequently asked questions
What is the difference between fossilsim and ss3diags?
Both compete on the same themes — r-package — within Analytics. fossilsim and ss3diags 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 fossilsim better than ss3diags?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. fossilsim and ss3diags are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
