cfr vs giscoR
A side-by-side editorial comparison of cfr and giscoR — release velocity, themes, recent moves, and the top alternatives to consider.
cfr vs giscoR: 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 giscoR?
giscoR's 1.0 moved its dataset index into the cache, so new Eurostat releases arrive without a package update.
giscoR downloads Eurostat GISCO administrative and statistical geodata — countries, NUTS regions, LAUs, urban audit units — as sf objects. The 1.0.0 release in December 2025 rebuilt the package on httr2, preferred GeoPackage downloads, reorganised the cache into topic folders, and moved the dataset database itself into the cache so it can be refreshed independently. Releases since have been a cache-persistence fix, a configurable timeout and an internals refactor.

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.

giscoR's 1.0 moved its dataset index into the cache, so new Eurostat releases arrive without a package update.
◆ Current state
giscoR downloads Eurostat GISCO administrative and statistical geodata — countries, NUTS regions, LAUs, urban audit units — as sf objects. The 1.0.0 release in December 2025 rebuilt the package on httr2, preferred GeoPackage downloads, reorganised the cache into topic folders, and moved the dataset database itself into the cache so it can be refreshed independently. Releases since have been a cache-persistence fix, a configurable timeout and an internals refactor.
◆ Where it's heading
The package is decoupling itself from Eurostat's publication calendar. Historically each new GISCO vintage required a release that bumped default years and rebuilt an internal dataset; after 1.0.0 a user can call gisco_get_cached_db(update_cache = TRUE) and reach new data without waiting. The follow-up releases are consistent with a project in consolidation — fixing the cache it just introduced, exposing a timeout for slow downloads, and tidying internals.
◆ Prediction
With the database now self-updating, expect releases to shift toward download reliability and new GISCO endpoints rather than annual dataset bumps; the timeout option in 1.1.0 suggests large downloads are the current pain point.
