EvoPhylo
EvoPhylo added BEAST2 alongside MrBayes, then went quiet for two years.
A side-by-side editorial comparison of epiworldR and geos — release velocity, themes, recent moves, and the top alternatives to consider.
epiworldR is a thin R shell whose releases track the C++ simulator underneath it
Almost every release here is a version bump of the underlying epiworld C++ library, wrapped and pushed to CRAN. The substantive R-side work is narrow and consistent: exposing simulation outputs that were already computed but not reachable from R — outbreak size, active cases, hospitalizations and their savers. The newest release addresses an AddressSanitizer finding, which is the kind of thing CRAN checks surface on a compiled package.
The thin GEOS binding for R adds terra interop after three years of compiler triage
geos is a low-overhead R binding to the GEOS geometry engine, exposing predicates, overlays and spatial indexes with minimal copying. Version 0.2.5 accepts terra SpatVector objects directly, alongside fixes for zero-length memcpy and plotting of invalid geometries. The releases between 0.2.0 and 0.2.5 contain almost no feature work — they are responses to compiler warnings, sanitiser findings and CRAN check failures.

The newest release addresses an AddressSanitizer finding, which is the kind of thing CRAN checks surface on a compiled package.
The R package's job is staying current with the simulator and satisfying CRAN, not evolving its own interface. What direction it has shows in which model outputs get exposed next, and in a steady tidy-up of the build — the custom configure script was dropped in favour of R's built-in C++17 and OpenMP settings, and test coverage has been filled in across several releases with automated assistance.
Expect the next release to track another epiworld version bump, with any R-side addition most likely being one more exposed metric or saver, following the pattern of get_hospitalizations and get_outbreak_size.
geos is a low-overhead R binding to the GEOS geometry engine, exposing predicates, overlays and spatial indexes with minimal copying.

The releases between 0.2.0 and 0.2.5 contain almost no feature work — they are responses to compiler warnings, sanitiser findings and CRAN check failures.
Feature development stopped after 0.2.0 and the package has since been kept alive against a moving toolchain: strict-prototypes warnings, a clang sanitiser error, format string checks, an M1 test failure. The 0.2.5 terra support breaks that pattern and came from an outside contributor, which suggests the package's direction is now set by what neighbouring spatial packages need from it rather than by GEOS feature coverage.
GEOS has released new capabilities since the 3.11 features wired up in 0.2.0, and none have been exposed since; whether the next release closes that gap or continues as interop-and-maintenance is the open question the history does not yet answer.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
Both compete on the same themes — r-package — within Analytics. epiworldR and geos 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. epiworldR and geos are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
