cfr vs CRediTas
A side-by-side editorial comparison of cfr and CRediTas — release velocity, themes, recent moves, and the top alternatives to consider.
cfr vs CRediTas: at a glance
What is cfr?
cfr packaged delay-corrected severity estimation, then went quiet on maintenance.
The package estimates disease severity and case ascertainment while correcting for the delay between a case being reported and its outcome being known. After the 0.1.1 rework of the estimation internals and a maintainer handover to Adam Kucharski, activity dropped to a vignette and an R-devel compatibility patch in February 2025.
What is CRediTas?
A CRediT author-statement generator that renamed itself, then went quiet for two years.
CRediTas turns a contributor-roles table into a CRediT Author Statement for a paper. The 0.2.0 release in April 2023 did the heavy lifting — package rename, a full object_verb() API rename, and output that drops straight into R Markdown or Quarto. The 0.3.0 release in August 2025 is the only activity since and carries no changelog text beyond a pointer to NEWS.md.

cfr packaged delay-corrected severity estimation, then went quiet on maintenance.
◆ Current state
The package estimates disease severity and case ascertainment while correcting for the delay between a case being reported and its outcome being known. After the 0.1.1 rework of the estimation internals and a maintainer handover to Adam Kucharski, activity dropped to a vignette and an R-devel compatibility patch in February 2025.
◆ Where it's heading
The methodological work is done and consolidated: likelihood approximation is now selected automatically from outbreak size and an initial severity estimate, and the internals were renamed with a dot prefix to close the public surface down to cfr_static(), cfr_rolling() and the data-preparation generic. Releases since have been documentation and compatibility only.
◆ Prediction
The 0.1.0 notes flagged time-varying ascertainment as future work and it has not appeared in the two releases since; nothing in these entries indicates when or whether it lands.
CRediTas
0.0ANALYTICS
A CRediT author-statement generator that renamed itself, then went quiet for two years.
◆ Current state
CRediTas turns a contributor-roles table into a CRediT Author Statement for a paper. The 0.2.0 release in April 2023 did the heavy lifting — package rename, a full object_verb() API rename, and output that drops straight into R Markdown or Quarto. The 0.3.0 release in August 2025 is the only activity since and carries no changelog text beyond a pointer to NEWS.md.
◆ Where it's heading
Development front-loaded a breaking cleanup during rOpenSci review and has coasted since. The design bet made in 0.2.0 — return a string for inline use rather than write a file — pointed the package at literate authoring workflows rather than at standalone scripts, and nothing since has moved away from it. The empty 0.3.0 note makes the current direction impossible to read from the feed.
◆ Prediction
Too little is published to call the next move; the 0.3.0 entry would need to carry its actual changes for the trajectory to be readable from the changelog at all.
