sofa vs spatsoc: at a glance
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 spatsoc?
One maintainer, one or two new collective-motion metrics per release, for two years straight
spatsoc turns animal relocation data into spatial and social groupings — dyads, fission-fusion events, group centroids — and the recent history is a metronomic accretion of collective-motion measures on top of that base. Since late 2024 nearly every release has added one or two: polarization, direction to leader, position along the group axis, directional correlation delay, edge alignment, edge zones. Development is essentially single-handed; almost every merged PR in this window carries the same author.

◆ 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.

◆ Current state
spatsoc turns animal relocation data into spatial and social groupings — dyads, fission-fusion events, group centroids — and the recent history is a metronomic accretion of collective-motion measures on top of that base.

Development is essentially single-handed; almost every merged PR in this window carries the same author.
◆ Where it's heading
The December 2025 release changes register. Alongside three new calc_distance / calc_direction / calc_centroid functions and an internal assertion family, it deprecates the `projection` argument in favour of `crs` and lands a round of checks and tests explicitly staged ahead of a new spatial interface. Read together, that is a package finishing its metric catalogue and starting to rework the coordinate-handling layer underneath it to match modern R-spatial conventions — the same evolution that made it drop its startup warning back in 0.2.7.
◆ Prediction
The next release is likely the spatial-interface rework the 0.2.12 test and assertion work was staged for, with `projection` moving from deprecated to removed. Feature additions should slow while that lands.
