paleobuddy vs Rpath
A side-by-side editorial comparison of paleobuddy and Rpath — release velocity, themes, recent moves, and the top alternatives to consider.
paleobuddy vs Rpath: at a glance
What is paleobuddy?
paleobuddy can now simulate trait-dependent diversification, not just birth-death.
paleobuddy simulates diversification, fossil records and phylogenetic trees, with rates that can be arbitrary functions of time — its founding idea, implemented through rexp.var() generalizing exponential and Weibull draws. The 1.1.0 release adds state-dependent speciation and extinction simulation at roughly MuHiSSE generality, and lets simulations stop at a target number of extant species instead of conditioning on time.
What is Rpath?
Rpath 1.1.0 learns to read Ecopath's own files, easing migration off the desktop tool.
Rpath is NOAA's R implementation of the Ecopath with Ecosim mass-balance equations for marine food web models. The feed is an archive backfill and arrives out of version order, with several entries carrying only a journal abstract instead of release notes. The substantive recent work is 1.0.0, which paired real ecosim bug fixes with the documentation and packaging expected of a 1.0, and 1.1.0, which adds .eiixml import and new balance estimation.

paleobuddy can now simulate trait-dependent diversification, not just birth-death.
◆ Current state
paleobuddy simulates diversification, fossil records and phylogenetic trees, with rates that can be arbitrary functions of time — its founding idea, implemented through rexp.var() generalizing exponential and Weibull draws. The 1.1.0 release adds state-dependent speciation and extinction simulation at roughly MuHiSSE generality, and lets simulations stop at a target number of extant species instead of conditioning on time.
◆ Where it's heading
Releases track the maintainer's publications rather than a product cadence — 1.0.0 accompanied the MEE manuscript, 1.0.0.1 exists purely as a Zenodo citation anchor, and 1.1.0 is stated as going with a paper on SSE model accuracy for trees including fossil data. That framing sets the direction: the package grows whichever capability the next study needs to test. The stated SSE limits, no quantitative traits and no cladogenetic transitions, mark exactly where that boundary currently sits.
◆ Prediction
Quantitative traits and cladogenetic transitions are named as missing, which makes them the obvious next targets, though on this history the timing will follow a paper rather than a roadmap.
Rpath
0.0ANALYTICS
Rpath 1.1.0 learns to read Ecopath's own files, easing migration off the desktop tool.
◆ Current state
Rpath is NOAA's R implementation of the Ecopath with Ecosim mass-balance equations for marine food web models. The feed is an archive backfill and arrives out of version order, with several entries carrying only a journal abstract instead of release notes. The substantive recent work is 1.0.0, which paired real ecosim bug fixes with the documentation and packaging expected of a 1.0, and 1.1.0, which adds .eiixml import and new balance estimation.
◆ Where it's heading
Development is moving from a faithful reimplementation of published equations toward a tool that can take over an existing modeling practice. Importing .eiixml files means models authored in the EwE desktop software no longer have to be rebuilt by hand, and the balance work reduces how many parameters a modeler must supply up front. The 1.0.0 release's contributor guidelines, issue templates and per-function examples point the same direction: preparing for users the maintainers do not personally know.
◆ Prediction
The next releases will likely widen the import path and tighten balance diagnostics, since 1.1.0 already spent effort on error messages for models missing parameters — the failure mode imported models will hit most.
