carrier vs crane
A side-by-side editorial comparison of carrier and crane — release velocity, themes, recent moves, and the top alternatives to consider.
carrier vs crane: at a glance
What is carrier?
carrier's 0.3.0 quietly rewrites how crated functions see each other — and breaks code that relied on the old rules.
carrier packages an R function together with the data it needs so it can be shipped to another process or machine. 0.3.0 changed the semantics of functions passed through ...: they are now re-crated inside the main crate environment instead of inheriting from wherever they were defined. That fixes helper functions failing to resolve each other remotely, and stops local environments dragging large objects into the payload.
What is crane?
Crane is turning into the table-and-plot layer for Roche's clinical output stack.
Crane publishes release candidates rather than finals, and the whole of 0.3.2 is carried by a single rc2 body — its two sibling tags are one-line styling commits, one of them tagged with an unsubstituted vX.Y.Z placeholder. The rc2 notes run to dozens of additions across regression tables, line plots and hierarchical rate tables.

◆ Current state
carrier packages an R function together with the data it needs so it can be shipped to another process or machine. 0.3.0 changed the semantics of functions passed through ...: they are now re-crated inside the main crate environment instead of inheriting from wherever they were defined. That fixes helper functions failing to resolve each other remotely, and stops local environments dragging large objects into the payload.
◆ Where it's heading
Each release tightens the boundary between a crate and its surroundings. 0.2.0 introduced .parent_env defaulting to baseenv() to cut the crate off from the global search path and made unnamed ... arguments an error instead of a silent drop; 0.3.0 finishes the job by controlling the environment chain of the packed closures themselves. The package is trading backwards compatibility for predictable, self-contained payloads — a reasonable bet for something whose failures otherwise surface on a remote worker.
◆ Prediction
The 0.1.0 notes promised an automatic dependency-detection mode to replace explicit packing; nothing since has delivered it, and with the environment semantics now settled that is the obvious next move — though the entries give no date for it.

Crane is turning into the table-and-plot layer for Roche's clinical output stack.
◆ Current state
Crane publishes release candidates rather than finals, and the whole of 0.3.2 is carried by a single rc2 body — its two sibling tags are one-line styling commits, one of them tagged with an unsubstituted vX.Y.Z placeholder. The rc2 notes run to dozens of additions across regression tables, line plots and hierarchical rate tables.
◆ Where it's heading
The package is moving from plotting helpers to a full analysis-output layer: mixed models for repeated measures, pairwise Cox results, risk-management-plan tables and adverse-event incidence rates all arrive in one cycle, and the annotation machinery underneath was rebuilt for reliable table-to-axis alignment. Defaults are being pulled toward SAS and rtables output — the log-rank test now uses survival::survdiff instead of coin, and survfit confidence intervals default to plain rather than log.
◆ Prediction
Expect a 0.3.2 final close behind rc2, and the deprecated g_lineplot() family to be removed once gg_lineplot() and annotate_gg() have settled.

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