microViz vs prospectr: at a glance
What is microViz?
Microbiome ordination and visualisation, in maintenance and keeping pace with vegan and ggplot2.
microViz provides visualisation and statistics for microbiome data built on phyloseq, including ordination exploration, distance-based dispersion analysis and composition plots. The release notes are pointer-style entries that name a pull request and link a comparison range rather than describing what changed, so most of what can be established from this feed is cadence and dependency pressure rather than substance. Version 0.13.1 is the exception, naming documentation work on dist_bdisp and its defaults relative to vegan's betadisper.
What is prospectr?
prospectr spent its biggest release in years fixing spectra it had been quietly mangling.
prospectr provides the signal-processing layer for near-infrared and visible spectroscopy in R — Savitzky-Golay and gap-segment derivatives, standard normal variate, detrending, continuum removal, splice correction, plus calibration sampling algorithms like Kennard-Stone and DUPLEX and readers for ASD and BUCHI NIRCal instrument files. The May release is the substantial one: a long list of corrections to functions that were returning wrong or missing values rather than failing.

microViz
0.0INFRA · APIS
Microbiome ordination and visualisation, in maintenance and keeping pace with vegan and ggplot2.
◆ Current state
microViz provides visualisation and statistics for microbiome data built on phyloseq, including ordination exploration, distance-based dispersion analysis and composition plots. The release notes are pointer-style entries that name a pull request and link a comparison range rather than describing what changed, so most of what can be established from this feed is cadence and dependency pressure rather than substance. Version 0.13.1 is the exception, naming documentation work on dist_bdisp and its defaults relative to vegan's betadisper.
◆ Where it's heading
Read through the dependency mentions, the pattern is a package spending its releases absorbing changes in the ecosystem beneath it: vegan deprecating summary in favour of scores, cowplot warning under ggplot2 3.5, testthat declarations centralised, CI actions updated. Nothing in the window indicates new analytical capability, and the 0.13.0 minor bump that would be the place to look for it ships with no notes at all. The honest reading is a stable package under maintenance by a single maintainer.
◆ Prediction
Expect continued upkeep against phyloseq, vegan and ggplot2 changes rather than a feature programme. Because the notes do not describe their own contents, a substantive release here would be indistinguishable from a maintenance one in this feed, so the direction cannot be read from these entries alone.
prospectr
0.0INFRA · APIS
prospectr spent its biggest release in years fixing spectra it had been quietly mangling.
◆ Current state
prospectr provides the signal-processing layer for near-infrared and visible spectroscopy in R — Savitzky-Golay and gap-segment derivatives, standard normal variate, detrending, continuum removal, splice correction, plus calibration sampling algorithms like Kennard-Stone and DUPLEX and readers for ASD and BUCHI NIRCal instrument files. The May release is the substantial one: a long list of corrections to functions that were returning wrong or missing values rather than failing.
◆ Where it's heading
The recent work is corrective rather than additive, and several items changed results silently before being caught. continuumRemoval() derived its convex-hull boundary offset from a fixed one-wavelength assumption that broke for fine-resolution spectra or non-nanometre units; cochranTest() passed an invalid argument name to prcomp() and produced incorrect principal component scores; readASD() silently dropped spectra in one branch of its text path. Two file readers were leaking connections. Alongside that runs a smaller thread of decoupling preprocessing steps from each other, most visibly detrend() gaining an snv argument so polynomial detrending can run without the SNV transform that Barnes et al. bundled with it.
◆ Prediction
The detrend() decoupling is the only recent addition and it fits a broader pipeline-composition direction, so similar separation of other bundled preprocessing steps is the plausible next move. The misspelled substraction argument now carries a deprecation warning, which schedules its removal for a future release.

Frequently asked questions
What is the difference between microViz and prospectr?
They serve adjacent needs but don't currently overlap on shipped themes. microViz and prospectr 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.
Is microViz better than prospectr?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. microViz and prospectr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
