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.

What is Tplyr?

Tplyr made clinical summary tables explain where every number came from.

Tplyr builds clinical summary tables through a layered grammar — count, descriptive statistics, and shift layers assembled onto a table object. The 1.0.0 release added a traceability metadata framework that lets a user ask which source rows produced any given cell, and later releases extended it to cases the first pass missed. The package is maintained by Atorus within the pharmaverse ecosystem.

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.

0.0

Tplyr made clinical summary tables explain where every number came from.

◆ Current state

Tplyr builds clinical summary tables through a layered grammar — count, descriptive statistics, and shift layers assembled onto a table object. The 1.0.0 release added a traceability metadata framework that lets a user ask which source rows produced any given cell, and later releases extended it to cases the first pass missed. The package is maintained by Atorus within the pharmaverse ecosystem.

◆ Where it's heading

Post-1.0 work has been about completing the metadata story and filling gaps in layer composition rather than adding table types — metadata for missing subjects, add_anti_join(), missing-subject rows, data limiting, and fixes to nested count layers where an inner value appears under several outer groups. Releases cluster tightly after a major version, then go quiet, and the window ends with a patch issued days after the release it corrects.

◆ Prediction

Further releases will most likely continue closing traceability and nested-layer edge cases rather than introducing new layer types, following the pattern of both post-1.0 feature releases.
