A side-by-side editorial comparison of EpiNow2 and gridpattern — release velocity, themes, recent moves, and the top alternatives to consider.
EpiNow2 unified its model interface, then went back to deepen the estimators behind it
EpiNow2 estimates reproduction numbers, infections and delay distributions from incomplete epidemiological reporting data. 1.8.0 was the structural turning point: every main modelling function now returns a consistent S3 object with `fit`, `args` and `observations`, reachable through shared accessors. The releases either side of it work on estimator quality — accumulation of irregularly reported data in 1.7.0, and a substantial expansion of `estimate_truncation()` in 1.9.0.
gridpattern keeps widening its catalogue, and the newest patterns finally use the device's own line rendering.
An R package supplying pattern fills for grid graphics — stripes, weaves, polygon tilings, images and placeholders. Releases are infrequent and irregular, roughly one or two a year with an eighteen-month gap before the most recent. The work divides between adding pattern types and making the existing ones behave consistently, particularly around units and how spacing parameters are interpreted.

The package spent this window paying down interface debt and is now extending from the tidier base. Options that existed only for `estimate_infections()` have been propagated outward: `estimate_truncation()` gained the full `dist_spec` delay families, `obs_opts()` observation model selection between Poisson and negative binomial, and the `likelihood` and `return_likelihood` settings that make prior-only fits and loo-compatible output possible. Hardcoded assumptions are being replaced by specifiable ones in the same motion — the truncation model's additive noise term was a fixed `sigma ~ normal(0, 1)` prior and is now a `dist_spec` argument.
Expect the remaining modelling functions to keep converging on the shared options interface, since the last two releases have each moved another function onto it. A new `estimate_dist()` for interval-censored linelist data suggests delay estimation is the area still gaining surface.

Two long-running efforts are visible. The first is unit consistency: v1.2.1 gave the geometry patterns a units parameter, v1.2.2 extended it to weave and fixed polygon tiling to respect it — the slow propagation of one design decision through a family of functions. The second is integration with R's own graphics capabilities, which reaches its clearest expression in v1.4.2's line pattern: rather than filling bands with solid colour as stripe does, it draws stroked lines through the device, so every built-in linetype including dotdash, twodash and custom hex specifications works. The package is also visibly maintaining its external dependencies, having rotated placeholder image services as hosts disappeared.
Expect further pattern types and continued propagation of the units parameter to any function still missing it; the entries give no indication of a change in the package's scope beyond pattern fills.
