hereR vs rollupTree
A side-by-side editorial comparison of hereR and rollupTree — release velocity, themes, recent moves, and the top alternatives to consider.
hereR vs rollupTree: at a glance
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 rollupTree?
The recursive-computation engine under massProps grows the accessors its consumer needed
rollupTree performs recursive computations over tree and DAG structures — the generic engine that its author's massProps package uses to roll mass properties up an assembly breakdown. It is small and moves slowly: five releases in a year, of which two are README and vignette work. The current surface added row-level get and set accessors by key and by id at 0.4.0.

hereR
0.0INFRA · APIS
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.
rollupTree

The recursive-computation engine under massProps grows the accessors its consumer needed
◆ Current state
rollupTree performs recursive computations over tree and DAG structures — the generic engine that its author's massProps package uses to roll mass properties up an assembly breakdown. It is small and moves slowly: five releases in a year, of which two are README and vignette work. The current surface added row-level get and set accessors by key and by id at 0.4.0.
◆ Where it's heading
The package develops in response to its one visible consumer. The 0.4.0 accessors appeared in January 2026 and massProps switched to them thirteen days later; 0.4.1 then fixed missing column names in the setters, which is the kind of defect only real use surfaces. Before that, 0.3.0's default_validate_dag() extended validation past strict trees to directed acyclic graphs, widening what structures the engine will accept.
◆ Prediction
On the established pattern the next release will be whatever massProps needs next, discovered by using it. A DAG validator suggests non-tree structures are in scope, but nothing in these notes says that path is being pushed further.

Frequently asked questions
What is the difference between hereR and rollupTree?
They serve adjacent needs but don't currently overlap on shipped themes. hereR and rollupTree 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 rollupTree?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. hereR and rollupTree are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
