giscoR vs serofoi
A side-by-side editorial comparison of giscoR and serofoi — release velocity, themes, recent moves, and the top alternatives to consider.
giscoR vs serofoi: at a glance
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.
What is serofoi?
serofoi grew a serosurvey simulator alongside the force-of-infection models it was built to fit.
serofoi estimates the force of infection from serological survey data using Bayesian serocatalytic models fitted through Stan. Beyond fitting it now simulates serosurveys — specifying a model and a survey design and generating the data such a survey would produce. The most recent release is visualisation and naming work.

giscoR

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.
serofoi
0.0ANALYTICS
serofoi grew a serosurvey simulator alongside the force-of-infection models it was built to fit.
◆ Current state
serofoi estimates the force of infection from serological survey data using Bayesian serocatalytic models fitted through Stan. Beyond fitting it now simulates serosurveys — specifying a model and a survey design and generating the data such a survey would produce. The most recent release is visualisation and naming work.
◆ Where it's heading
The package moved from fitting-only to a fit-and-simulate pair. 0.1.0 added simulation from time- or age-varying force-of-infection trends and simplified the fitted object down to a Stan fit; 1.0.2 broadened simulation into full serosurvey generation with its own vignette. 1.0.3 then spent its effort on naming consistency and plotting options, which is what a package does once its scope is set.
◆ Prediction
With simulation and fitting both in place, the natural next step is tooling that closes the loop between them — recovery checks or study-design guidance built on simulated surveys.
