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 RStudio?

RStudio ships through release branches, and the notes are commit messages

RStudio's feed is a run of release-branch tags — Yellow Yarrow, Pacific Dogwood, Golden Wattle — each carrying a backported fix rather than an announced feature. The newest tag restores a Windows install rule that had been deleted alongside an unrelated winpty block, leaving the shipped installer without a 32-bit rsession binary and breaking 32-bit R entirely. What reaches users is legible only if you read the commit body.

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.

RStudio ships through release branches, and the notes are commit messages

◆ Current state

RStudio's feed is a run of release-branch tags — Yellow Yarrow, Pacific Dogwood, Golden Wattle — each carrying a backported fix rather than an announced feature. The newest tag restores a Windows install rule that had been deleted alongside an unrelated winpty block, leaving the shipped installer without a 32-bit rsession binary and breaking 32-bit R entirely. What reaches users is legible only if you read the commit body.

◆ Where it's heading

Two areas absorb nearly all the visible work: Windows packaging correctness and Posit Assistant plumbing — SHA-256 verification of assistant downloads, gating .positai/.claude ignore-file edits on the directories actually existing. Both read as cleanup after features landed elsewhere. The release-branch structure means the same fix often appears twice, once on main and once backported, so tag count overstates the pace of change.

◆ Prediction

Expect further Yellow Yarrow tags in the same shape — a single backported fix per tag, its description written for reviewers rather than users. Posit Assistant integration is the most likely source of the next visible change, since it is the only area here still gaining behavior rather than losing bugs.
