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 sofa?

A CouchDB client for R whose recent work is all test infrastructure, not new routes.

sofa wraps the CouchDB HTTP API for R — database and document CRUD, Mango queries and indexes, design documents, replication, and attachments, organized around a Cushion connection object. Feature development effectively stopped after 0.4.0 brought CouchDB v3 compatibility in 2020. The two 2026 releases are a testing and packaging overhaul: 0.4.1 rebuilt the suite around a crul-mocked fake CouchDB so tests no longer need Cloudant or a local Docker instance, reaching 100% coverage, and 0.4.2 cleared CRAN check notes.

ANALYTICS
0.0

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.

2.5

A CouchDB client for R whose recent work is all test infrastructure, not new routes.

◆ Current state

sofa wraps the CouchDB HTTP API for R — database and document CRUD, Mango queries and indexes, design documents, replication, and attachments, organized around a Cushion connection object. Feature development effectively stopped after 0.4.0 brought CouchDB v3 compatibility in 2020. The two 2026 releases are a testing and packaging overhaul: 0.4.1 rebuilt the suite around a crul-mocked fake CouchDB so tests no longer need Cloudant or a local Docker instance, reaching 100% coverage, and 0.4.2 cleared CRAN check notes.

◆ Where it's heading

This is a rOpenSci package being brought back to a maintainable state rather than extended. The 0.4.1 decision to mock the server is the consequential one — it decouples CI from a live CouchDB, which is what made the cross-platform GitHub Actions workflow and full coverage possible at all. Two genuine bugs surfaced in that process, in db_replicate() URL construction against non-Cloudant servers and db_alldocs(disk=) not returning the documented file path, suggesting the untested paths had drifted.

◆ Prediction

With the test harness now self-contained, the next plausible move is catching up on CouchDB routes added since v3 rather than further infrastructure work, though nothing in these entries commits to it.
