PurpleAir
The R client for PurpleAir sensors keeps finding its time-averaging was wrong.
A side-by-side editorial comparison of quantmod and r-owidapi — release velocity, themes, recent moves, and the top alternatives to consider.
The R finance workhorse spends its releases absorbing what data vendors break
quantmod pulls market data into R and charts it, and has been in maintenance for years. The last six releases are dominated by upstream breakage: Yahoo Finance crumb authentication, a batch-size ceiling dropping from 199 to 99 symbols, GDPR consent failures, repeated URL changes at FRED and OANDA. Genuine additions are rare and small — a ClOp() return function, an intraday endpoint, better ambiguous-column detection.
The R client for Our World in Data found its search had been reading a tenth of the catalog.
owidapi is a small R client for Our World in Data, covering chart data retrieval, metadata, the full chart catalog, and search over it, with experimental Shiny output helpers. It is three releases old and the most recent one is almost entirely repair: the catalog function was silently truncating at 1000 rows because of a Datasette row cap, which meant search had been operating on a fraction of what exists.

The pattern is a package whose cadence is set by other people's API changes rather than its own roadmap. Releases arrive when a data source breaks, and the changelog reads as a list of reports from users who hit the failure first. The FRED API key requirement in the latest release is the same story again — a free source adding registration, and quantmod adding an argument and a nudge to comply. Deprecation work on as.zoo.data.frame has been running since at least 0.4.27 without completing.
Nothing in these entries points to a planned feature; the next release will most likely be triggered by whichever vendor endpoint changes first.

Development is about making a thin wrapper trustworthy against an upstream that moves without notice. The truncation fix pages through the catalog properly; a separate fix stops the function breaking when Our World in Data dropped a column, by parsing typed columns only when present. Tests moved to mocked responses, with a small live suite retained purely to detect schema drift and skipped on CRAN — a sensible design for a package whose main risk is that the API changes shape rather than that the code is wrong. The user-facing surface has not grown since the initial release; the work is in defending it.
On this pattern the next release is likelier to be another upstream-compatibility fix than new functionality, with the schema-drift tests the mechanism that surfaces it.
