popbayes vs r2dii.analysis: at a glance
What is popbayes?
A wildlife population-trend package in low-maintenance mode.
popbayes fits Bayesian trends to animal population count series that mix ground counts, aerial counts and expert estimates. The visible history is short and slow: three releases across four years, with the most recent, 1.3, swapping usethis for cli in error messages and tidying the website. The substantive work in the window is 1.1, which reorganised how format_data() handles a dataset.
What is r2dii.analysis?
The climate-alignment maths behind PACTA, now stable and maintained rather than reshaped
r2dii.analysis computes the target-setting side of PACTA: market-share and sectoral decarbonisation targets that measure a loan book or portfolio against climate scenarios. It sits downstream of the matched company data the sibling packages produce. The 0.5.0 release declared it lifecycle-stable and handed maintenance to a new lead, and releases since have been narrow corrections rather than new methods.

A wildlife population-trend package in low-maintenance mode.
◆ Current state
popbayes fits Bayesian trends to animal population count series that mix ground counts, aerial counts and expert estimates. The visible history is short and slow: three releases across four years, with the most recent, 1.3, swapping usethis for cli in error messages and tidying the website. The substantive work in the window is 1.1, which reorganised how format_data() handles a dataset.
◆ Where it's heading
Development has settled into maintenance carried largely by outside contributors, with the current release consisting of a dependency swap and message fixes from two different contributors. The one release with real design work, 1.1, moved format_data() from operating on a whole dataset to operating per count series, letting different series of the same species carry different conversion assumptions. Nothing since has changed the modelling surface.
◆ Prediction
The entries do not support a confident prediction beyond further contributor-driven maintenance; there is no visible signal of new modelling work.

The climate-alignment maths behind PACTA, now stable and maintained rather than reshaped
◆ Current state
r2dii.analysis computes the target-setting side of PACTA: market-share and sectoral decarbonisation targets that measure a loan book or portfolio against climate scenarios. It sits downstream of the matched company data the sibling packages produce. The 0.5.0 release declared it lifecycle-stable and handed maintenance to a new lead, and releases since have been narrow corrections rather than new methods.
◆ Where it's heading
The history is a package converging. Early releases churn the output contract of target_market_share() and target_sda() — which sectors appear, which years, how missing production is treated — and each change alters the numbers users get. The ald-to-abcd rename runs across several releases before completing, and by 0.5.0 the churn has stopped, with three older summarise functions soft-deprecated and the package marked stable. What remains is edge-case correctness in target coverage.
◆ Prediction
With the package marked stable and the terminology migration finished, the soft-deprecated summarise functions are the obvious next thing to remove outright.
