affiner vs mapSpain: at a glance
What is affiner?
affiner is quietly turning a grid transformation helper into a small computational geometry library.
An R package that began as a wrapper around grid's affine transformation primitives, with an angle vector class supporting degrees, radians, half-turns, turns and gradians so users need not convert by hand. Four releases in roughly eighteen months. The recent two have expanded well past that starting point into geometric objects and the predicates that operate on them.
What is mapSpain?
mapSpain's 1.0.0 broke every user cache to get the package onto modern foundations.
mapSpain provides administrative boundaries, tile providers and geographic dictionaries for Spain, pulling from GISCO, SIANE, INE and IGN sources. The 1.0.0 release in January 2026 rebuilt it: requests moved to httr2, the cache reorganized into topic-based subfolders under tools::R_user_dir() instead of rappdirs, R 4.1 became the floor, and every function now returns tidy objects. Existing caches are explicitly incompatible and must be rebuilt.

affiner is quietly turning a grid transformation helper into a small computational geometry library.
◆ Current state
An R package that began as a wrapper around grid's affine transformation primitives, with an angle vector class supporting degrees, radians, half-turns, turns and gradians so users need not convert by hand. Four releases in roughly eighteen months. The recent two have expanded well past that starting point into geometric objects and the predicates that operate on them.
◆ Where it's heading
The direction is clear from the order things arrived. Version 0.2.1 added the predicate layer first — has_intersection(), intersection(), is_equivalent() and is_parallel() as S3 generics working across angle vectors, points, lines and planes. Version 0.3.1 then supplied the objects those generics need, with Ellipse2D, Polygon2D and Segment2D R6 classes plus constructors for rectangles, regular n-gons and isotoxal star polygons, and dot products at one, two and three dimensions. Building the operations before the shapes is unusual ordering but it means each new object type arrives already composable with everything else.
◆ Prediction
Expect more 2D and 3D object types filling out the same generic interface, and the geometry side to keep outgrowing the grid-transformation wrapper the package was named for.
mapSpain
0.0ANALYTICS
mapSpain's 1.0.0 broke every user cache to get the package onto modern foundations.
◆ Current state
mapSpain provides administrative boundaries, tile providers and geographic dictionaries for Spain, pulling from GISCO, SIANE, INE and IGN sources. The 1.0.0 release in January 2026 rebuilt it: requests moved to httr2, the cache reorganized into topic-based subfolders under tools::R_user_dir() instead of rappdirs, R 4.1 became the floor, and every function now returns tidy objects. Existing caches are explicitly incompatible and must be rebuilt.
◆ Where it's heading
The package has finished its modernization and moved into consolidation. 1.1.0 added a configurable query timeout and pinned httr2 for compatibility with giscoR, the sibling package it shares plumbing with; 1.2.0 was a declared internal-only refactor with the public API held fixed and the work described as AI-assisted with human review. The data-source expansion that characterized the 0.9.x and 0.10.x line — comarcas by type, simplified INE geometries, SIANE vintages — has paused while the foundations settle.
◆ Prediction
Expect a return to source coverage now that the refactor is done: new SIANE or INE vintages and additional boundary types are the pattern this package has repeated. The entries show no further architectural work queued.
