formr vs GeoThinneR: at a glance
What is formr?
formr's R client reached CRAN and moved its recommended path to the v1 REST API.
formr is the R-side client for formr.org, the open study framework used to run longitudinal and experience-sampling questionnaires. In May it reached CRAN for the first time, released in step with formr.org server v1.0.0, and the formr_api_* family built on the server's RESTful surface became the supported entry point. The three releases since have been repair work on the paths that move rendered output and API results.
What is GeoThinneR?
Spatial thinning grows a result object, and the API breaks to make room for it
GeoThinneR removes spatially redundant occurrence records before species distribution modelling. Version 2.0.0 restructured it around a GeoThinned S3 class with print, summary, plot and trial-accessor methods, replacing the bare logical vectors earlier versions returned, and reorganised the methods into three named strategies — distance, grid and precision — with the search algorithm as a separate argument. The two releases since have added a priority system for choosing which of several tied points to drop.

formr's R client reached CRAN and moved its recommended path to the v1 REST API.
◆ Current state
formr is the R-side client for formr.org, the open study framework used to run longitudinal and experience-sampling questionnaires. In May it reached CRAN for the first time, released in step with formr.org server v1.0.0, and the formr_api_* family built on the server's RESTful surface became the supported entry point. The three releases since have been repair work on the paths that move rendered output and API results.
◆ Where it's heading
The direction is consolidation around the v1 API while the legacy Classic path is left running but demoted in the vignette. The complication is that CRAN's requirements and the OpenCPU server's requirements pull against each other: CRAN review pushed rendering into tempdir() with random filenames, which broke rforms.org because the server fetches a fixed knit.html, and 1.1.2 had to put it back. The 1.2.0 note describes the same write-directory problem being solved in an OpenCPU-aware way rather than reverted, alongside making dependencies installable under WASM.
◆ Prediction
Two of the last three releases were regressions in the render path, so the OpenCPU-aware write directory in 1.2.0 is the change most likely to need follow-up. The Classic formr_results() path remains in the package with no removal date announced, and nothing in these entries indicates when that ends.

Spatial thinning grows a result object, and the API breaks to make room for it
◆ Current state
GeoThinneR removes spatially redundant occurrence records before species distribution modelling. Version 2.0.0 restructured it around a GeoThinned S3 class with print, summary, plot and trial-accessor methods, replacing the bare logical vectors earlier versions returned, and reorganised the methods into three named strategies — distance, grid and precision — with the search algorithm as a separate argument. The two releases since have added a priority system for choosing which of several tied points to drop.
◆ Where it's heading
The package is moving from a function that returns an answer to a tool that returns something you can interrogate. Multiple thinning trials are first-class — you can ask for the largest, fetch a specific one, summarise one — and the recent work is about making the choice among tied candidates controllable rather than random. Dependency discipline runs alongside: the R-tree method was dropped when its package was not on CRAN, and spatial coverage degrades to NA rather than failing when s2 is missing.
◆ Prediction
The priority mechanism now covers all three strategies and the last release was an overflow fix in the local kd-tree path at large sizes, so scale is where the pressure is. More work on the distance methods at large N is the likelier next step than another strategy.

Frequently asked questions
What is the difference between formr and GeoThinneR?
They serve adjacent needs but don't currently overlap on shipped themes. formr and GeoThinneR 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.
Is formr better than GeoThinneR?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. formr and GeoThinneR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
