ggVennDiagram vs prospectr
A side-by-side editorial comparison of ggVennDiagram and prospectr — release velocity, themes, recent moves, and the top alternatives to consider.
ggVennDiagram vs prospectr: at a glance
What is ggVennDiagram?
A Venn diagram package whose public release notes say almost nothing — including about its copyright cleanup.
ggVennDiagram draws Venn diagrams as ggplot2 objects. The visible release feed is thin and irregular: three entries between 2021 and 2024, two of which contain nothing but a pointer to NEWS. Only the most recent, V1.5, describes actual changes, and both of them are legal housekeeping rather than features.
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.

ggVennDiagram
0.0INFRA · APIS
A Venn diagram package whose public release notes say almost nothing — including about its copyright cleanup.
◆ Current state
ggVennDiagram draws Venn diagrams as ggplot2 objects. The visible release feed is thin and irregular: three entries between 2021 and 2024, two of which contain nothing but a pointer to NEWS. Only the most recent, V1.5, describes actual changes, and both of them are legal housekeeping rather than features.
◆ Where it's heading
What can be read here is not a feature direction but a tidying of provenance. V1.5 removed code copied from yulab.utils and made the package comply with the copyright terms of the venn package it draws on, with the yulab.utils maintainer appearing as a first-time contributor to do it. Everything else in the window defers to a changelog kept outside the feed, so the direction of the package itself is not readable from these entries.
◆ Prediction
No reliable prediction is available from this feed — the release notes are pointers rather than descriptions, and the visible entries skip whole version ranges.
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.
