What is hereR?

An R client for HERE's location APIs, shaped almost entirely by what the vendor exposes next.

hereR wraps HERE's routing, isoline, traffic, weather and geocoding endpoints for R, returning sf objects. Development is steady and reactive: each release either adopts a transport mode, parameter or API version HERE has newly made available, or corrects a rate limit that was producing 429 errors in practice. The current release adds speed-limit control and five more isoline transport modes.

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.

An R client for HERE's location APIs, shaped almost entirely by what the vendor exposes next.

◆ Current state

hereR wraps HERE's routing, isoline, traffic, weather and geocoding endpoints for R, returning sf objects. Development is steady and reactive: each release either adopts a transport mode, parameter or API version HERE has newly made available, or corrects a rate limit that was producing 429 errors in practice. The current release adds speed-limit control and five more isoline transport modes.

◆ Where it's heading

Two threads run through the whole history. One is coverage — new modes, tolls and currency, arrival times, speed limits — arriving in the package shortly after they appear in HERE's API. The other is defensive operational tuning, with request rates repeatedly lowered below HERE's documented limits because the documented limits do not hold up. 1.0.0 was the one moment the package had to move rather than choose, migrating traffic to v7 and weather to v3 and breaking three functions' output in the process.

◆ Prediction

Expect the next release to enable whatever HERE exposes next in routing or isolines, and to keep adjusting request rates empirically; the package's own design appears settled.

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 hereR and prospectr?

They serve adjacent needs but don't currently overlap on shipped themes. hereR 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 hereR better than prospectr?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. hereR and prospectr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
