crane vs watcher
A side-by-side editorial comparison of crane and watcher — release velocity, themes, recent moves, and the top alternatives to consider.
crane vs watcher: at a glance
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.
What is watcher?
watcher is a thin filesystem-events binding whose releases are mostly build work.
The package wraps libfswatch in an R6 Watcher class for monitoring files and directories. Seven releases over sixteen months have added a vector path argument and two accessor methods, and spent the rest of their effort on build portability — non-standard system library locations, Windows bi-arch source builds on old rtools, and most recently removing the cmake requirement so the bundled source compiles with the R toolchain alone.

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.
watcher
0.0INFRA · APIS
watcher is a thin filesystem-events binding whose releases are mostly build work.
◆ Current state
The package wraps libfswatch in an R6 Watcher class for monitoring files and directories. Seven releases over sixteen months have added a vector path argument and two accessor methods, and spent the rest of their effort on build portability — non-standard system library locations, Windows bi-arch source builds on old rtools, and most recently removing the cmake requirement so the bundled source compiles with the R toolchain alone.
◆ Where it's heading
The API is deliberately small and appears finished; the work that remains is making the C dependency install cleanly everywhere. Dropping cmake follows the same move nanonext made, which is not a coincidence — both come from the same author and both are aiming at environments where installing a build system is not an option.
◆ Prediction
With cmake gone and the bundled library current, further releases are most likely to track libfswatch upstream rather than extend the R interface.
