A side-by-side editorial comparison of epiworldR and stockplotr — 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.
A stock-assessment plotting package is growing a table engine to match its figures.
stockplotr generates the figures and, since 0.8.0-beta, the tables that go into NOAA fisheries stock assessment reports. The 0.8.0 release swapped the table backend from flextable to gt and shipped table_landings() as the first table function; 0.9.0 exported it with an interface deliberately mirroring the plot functions. Alongside that, convert_output() moved in from the sister package asar so model output is standardized here rather than upstream.

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.
stockplotr generates the figures and, since 0.8.0-beta, the tables that go into NOAA fisheries stock assessment reports. The 0.8.0 release swapped the table backend from flextable to gt and shipped table_landings() as the first table function; 0.9.0 exported it with an interface deliberately mirroring the plot functions. Alongside that, convert_output() moved in from the sister package asar so model output is standardized here rather than upstream.
The package is consolidating the whole report-artifact pipeline in one place: standardize model output, then emit both figures and tables from the same long-format frame. Pulling convert_output() out of asar because stockplotr depended on it more heavily is the clearest signal of where the center of gravity now sits. Everything is still tagged beta, and the plot function count is growing faster than the table one.
More table_* functions built on the gt foundation are the obvious next step, matching the existing plot_* set; the 0.9.0 notes describe table_landings() as the first of a revamped family rather than a one-off.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. epiworldR and stockplotr 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 stockplotr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
