What is dialr?

The R phone-number package stopped only parsing numbers and started asking them where they are.

dialr wraps Google's libphonenumber through rJava, giving R a phone vector class that parses, validates and formats international numbers. It has been quiet since August 2022, when the last release removed a pathology where Java would freeze after enough invalid inputs. The package covers parsing, validation, formatting, and the metadata lookups added in 0.3.0.

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.

The R phone-number package stopped only parsing numbers and started asking them where they are.

◆ Current state

dialr wraps Google's libphonenumber through rJava, giving R a phone vector class that parses, validates and formats international numbers. It has been quiet since August 2022, when the last release removed a pathology where Java would freeze after enough invalid inputs. The package covers parsing, validation, formatting, and the metadata lookups added in 0.3.0.

◆ Where it's heading

Two forces shape the history. One is expansion into what libphonenumber knows beyond the number itself — carrier, geocode, timezone — which happened once, in 2019, and has not been extended since. The other is the ongoing cost of being a Java wrapper inside an R tidyverse: rJava initialisation moved so the :: form works, phone vectors reclassified when tibble 3.0.0 changed how it treats list-based classes, and repeated performance work to make crossing the Java boundary tolerable. The maintainer has floated moving the phone class onto vctrs but has not.

◆ Prediction

The vctrs migration is the one change the maintainer has explicitly signalled, and the hard-deprecated one-shot functions were slated for removal in the next major release; three years of silence make neither imminent.

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.
