PurpleAir
The R client for PurpleAir sensors keeps finding its time-averaging was wrong.
A side-by-side editorial comparison of discretefdr and quantmod — release velocity, themes, recent moves, and the top alternatives to consider.
The discrete-data FDR package is being pared into one piece of a larger multiple-testing suite.
DiscreteFDR implements false discovery rate procedures adapted for discrete test statistics, where the standard continuous-case corrections are conservative. It now covers a discrete Benjamini-Yekutieli procedure alongside the Benjamini-Hochberg variants it started with, including adaptive versions. Its datasets and test-result classes have been moved out into companion packages, so it increasingly does one job and defers the rest.
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 direction is decomposition into a suite. The amnesia dataset went to DiscreteDatasets, summary output now interoperates with the DiscreteTestResults class from DiscreteTests, and match.pvals() stopped being exported — each release trims something that belongs elsewhere. What remains gets methodological additions at a slow, deliberate cadence, with performance work on the step-up procedures that dominate cost when the number of tests is large. Recent activity is maintenance: replacing deprecated calls the package still made of its own siblings. This is a mature statistical package whose release notes are short because the methods underneath them are settled.
Expect further alignment with the companion packages rather than new procedures, since the last substantive release was already about interoperating with DiscreteTests classes and the most recent one about clearing deprecations.

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.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
Both compete on the same themes — r-package — within Analytics. discretefdr and quantmod are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. discretefdr and quantmod are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
