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 modsem?

modsem is grinding latent interaction models toward Mplus parity, one estimator at a time.

modsem fits interaction and quadratic effects between latent variables in R, offering both product-indicator approaches (modsem_pi) and distribution-analytic ones (modsem_da, covering LMS and QML). Releases land roughly monthly and are dense pull-request lists. The recent line is dominated by the LMS approach: gradient refactors, parallel E-steps, composite construct support, and careful handling of residual covariances between latent variables.

0.0

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.

modsem is grinding latent interaction models toward Mplus parity, one estimator at a time.

◆ Current state

modsem fits interaction and quadratic effects between latent variables in R, offering both product-indicator approaches (modsem_pi) and distribution-analytic ones (modsem_da, covering LMS and QML). Releases land roughly monthly and are dense pull-request lists. The recent line is dominated by the LMS approach: gradient refactors, parallel E-steps, composite construct support, and careful handling of residual covariances between latent variables.

◆ Where it's heading

Two things are being closed at once. The modelling gap — composites and formative constructs, categorical estimators, residual covariances in every direction, multigroup and clustered designs — brings modsem toward what commercial Mplus users expect, and the package's Mplus bridge is maintained alongside it, now with unique file IDs and a cleanup argument. The performance gap is the other: memoised H0, parallel E-step, optimized gradients and Hessians for both LMS and QML, all aimed at the distribution-analytic estimators that are expensive by construction. Convention borrowing from lavaan continues in message formatting and standard-error defaults.

◆ Prediction

The 1.0.20 and 1.0.21 releases both spent effort on residual covariances between endogenous and exogenous latent variables across estimation, prediction and standardization, and that thread has not obviously closed. The arrival of a second contributor moving MplusAutomation to Suggests suggests dependency trimming continues.

Frequently asked questions

What is the difference between hereR and modsem?

They serve adjacent needs but don't currently overlap on shipped themes. hereR and modsem 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 modsem?

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