cIRT
A choice-based IRT model published once in 2019 and kept compiling ever since
A side-by-side editorial comparison of ddpcr and popbayes — release velocity, themes, recent moves, and the top alternatives to consider.
A decade-old droplet PCR analysis package woken up for one compatibility release
ddpcr reads droplet digital PCR data exported from Bio-Rad's QuantaSoft, classifies droplets and ships a Shiny interface over the analysis. It has been on CRAN since 2016 alongside an F1000Research paper. The last ten years of releases are almost entirely about keeping pace with QuantaSoft export formats and with churn in its own R dependencies.
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.

The last ten years of releases are almost entirely about keeping pace with QuantaSoft export formats and with churn in its own R dependencies.
This is a maintained-not-developed package, and the release history shows it plainly: a burst of real work through 2016 and 2017, then long silences broken by releases whose stated purpose is staying on CRAN. The 2026 release fits the same shape but does more than the 2023 pair did, adding support for a QuantaSoft variant and finally retiring dplyr code written against a tidy evaluation style that has been outdated for years.
Nothing in the entries points to new analysis capability; the pattern suggests the package surfaces again only when a QuantaSoft export change or a dependency deprecation forces it.
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.
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.
The entries do not support a confident prediction beyond further contributor-driven maintenance; there is no visible signal of new modelling work.

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