giscoR vs mlr3fda: 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 mlr3fda?
A functional-data feature factory for mlr3, shipping a new extractor almost every month.
mlr3fda adds functional data support to mlr3 pipelines through PipeOps that turn functional columns into tabular features. Five releases since March 2026 have taken it from Fourier features to a catalogue covering wavelets, derivatives, depth, registration, integration and the catch22 time-series feature set. Development tracks the {tf} package closely.

giscoR
0.0ANALYTICS
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.
mlr3fda
2.5ANALYTICS
A functional-data feature factory for mlr3, shipping a new extractor almost every month.
◆ Current state
mlr3fda adds functional data support to mlr3 pipelines through PipeOps that turn functional columns into tabular features. Five releases since March 2026 have taken it from Fourier features to a catalogue covering wavelets, derivatives, depth, registration, integration and the catch22 time-series feature set. Development tracks the {tf} package closely.
◆ Where it's heading
The pattern is one or two new PipeOps per release with fixes to the previous batch alongside — Fourier in 0.4.0, registration in 0.5.0, depth and derivatives in 0.6.0, catch22 and integration in 0.7.0. Performance and parallel-safety work is folded in as it becomes necessary rather than deferred, as with the Fourier speedup and the mlr_reflections registration fix.
◆ Prediction
The extraction catalogue is filling out along established functional-data methods, so further tf-backed PipeOps are the likely next additions; the {tf} 0.5.0 compatibility release suggests upstream churn will keep setting the pace.
