affiner vs gridpattern
A side-by-side editorial comparison of affiner and gridpattern — release velocity, themes, recent moves, and the top alternatives to consider.
affiner vs gridpattern: 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 gridpattern?
gridpattern keeps widening its catalogue, and the newest patterns finally use the device's own line rendering.
An R package supplying pattern fills for grid graphics — stripes, weaves, polygon tilings, images and placeholders. Releases are infrequent and irregular, roughly one or two a year with an eighteen-month gap before the most recent. The work divides between adding pattern types and making the existing ones behave consistently, particularly around units and how spacing parameters are interpreted.

◆ 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.

gridpattern keeps widening its catalogue, and the newest patterns finally use the device's own line rendering.
◆ Current state
An R package supplying pattern fills for grid graphics — stripes, weaves, polygon tilings, images and placeholders. Releases are infrequent and irregular, roughly one or two a year with an eighteen-month gap before the most recent. The work divides between adding pattern types and making the existing ones behave consistently, particularly around units and how spacing parameters are interpreted.
◆ Where it's heading
Two long-running efforts are visible. The first is unit consistency: v1.2.1 gave the geometry patterns a units parameter, v1.2.2 extended it to weave and fixed polygon tiling to respect it — the slow propagation of one design decision through a family of functions. The second is integration with R's own graphics capabilities, which reaches its clearest expression in v1.4.2's line pattern: rather than filling bands with solid colour as stripe does, it draws stroked lines through the device, so every built-in linetype including dotdash, twodash and custom hex specifications works. The package is also visibly maintaining its external dependencies, having rotated placeholder image services as hosts disappeared.
◆ Prediction
Expect further pattern types and continued propagation of the units parameter to any function still missing it; the entries give no indication of a change in the package's scope beyond pattern fills.
