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.

What is vcmeta?

A meta-analysis toolkit still renaming its own API as it adds effect sizes.

vcmeta provides confidence-interval methods for meta-analysis across correlations, proportions, odds ratios, standardized mean differences and reliability, plus replication-study counterparts to most of them. Each release both widens the function inventory and reshuffles it. The most recent one adds agreement and generalised log-average functions while deleting one function and renaming six others.

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.

A meta-analysis toolkit still renaming its own API as it adds effect sizes.

◆ Current state

vcmeta provides confidence-interval methods for meta-analysis across correlations, proportions, odds ratios, standardized mean differences and reliability, plus replication-study counterparts to most of them. Each release both widens the function inventory and reshuffles it. The most recent one adds agreement and generalised log-average functions while deleting one function and renaming six others.

◆ Where it's heading

The package is converging on a naming scheme, with odds becoming oddsratio and ratio.prop2 becoming propratio2, and it is willing to break calling code to get there. Two of the last three releases carry a self-declared breaking parameter change, both cases where an assumption that used to be baked in became something the user must supply. Growth in the function set is steady rather than directional.

◆ Prediction

Expect the renaming pass to continue into the remaining inconsistent names, alongside more replication-study counterparts to existing estimators.
