What is rlistings?

Clinical listings that keep inheriting their hardest problem — pagination — from the layer below.

rlistings renders clinical-trial subject listings and paginates them for regulatory output, sitting alongside rtables on the shared formatters engine. The releases in this window are dominated by pagination correctness: repeated key columns across pages, splitting by a variable, ordered-factor handling, column gaps, and font metrics. Development is a large rotating contributor set inside the insightsengineering organisation.

What is S7?

S7 has stopped adding surface and started proving it holds up against R itself.

S7 is R's third-generation object system, built to unify the S3 and S4 lineages rather than add a fourth. The design work landed in 0.2.0, which reworked the default constructor, extended base-class coverage, and added a backward-compatibility shim so `@` property access works on R older than 4.3. Everything since has been maintenance: property setters gained a `check` escape hatch, and two consecutive releases exist mainly to keep the package compiling against R-devel 4.6.

Clinical listings that keep inheriting their hardest problem — pagination — from the layer below.

◆ Current state

rlistings renders clinical-trial subject listings and paginates them for regulatory output, sitting alongside rtables on the shared formatters engine. The releases in this window are dominated by pagination correctness: repeated key columns across pages, splitting by a variable, ordered-factor handling, column gaps, and font metrics. Development is a large rotating contributor set inside the insightsengineering organisation.

◆ Where it's heading

The package is progressively delegating pagination to formatters rather than implementing it — paginate_listing() was refactored to call formatters' paginate_to_mpfs() directly, and truetype font support arrived through a new formatters API. That reduces duplicated logic but ties the package's page-break behaviour to a dependency it shares with rtables. Feature work beyond pagination is thin: better error messages for unsupported column classes, a cheatsheet.

◆ Prediction

Expect pagination fidelity to remain the focus, with changes arriving as formatters exposes more of its layout machinery rather than as rlistings-native features.

S7 has stopped adding surface and started proving it holds up against R itself.

◆ Current state

S7 is R's third-generation object system, built to unify the S3 and S4 lineages rather than add a fourth. The design work landed in 0.2.0, which reworked the default constructor, extended base-class coverage, and added a backward-compatibility shim so `@` property access works on R older than 4.3. Everything since has been maintenance: property setters gained a `check` escape hatch, and two consecutive releases exist mainly to keep the package compiling against R-devel 4.6.

◆ Where it's heading

The changelog is thinning by design — 0.1.0 was a months-long feature dump, 0.2.0 a coordinated architectural revision, 0.2.2 a single line about internal R-devel support. That shape usually means an API the maintainers consider settled, where the remaining work is tracking the host language rather than extending the system. The one recurring theme is validation cost: repeated releases have made validation less frequent, more targeted, or skippable outright.

◆ Prediction

Expect continued small releases pinned to R-devel changes rather than new class-system features, with any further movement most likely in the validation and property-setter path that the last two feature changes both touched.
