What is inlabru?

A Bayesian spatial modelling package rebuilding its foundations one breaking release at a time

inlabru wraps INLA for spatial, point-process and latent-Gaussian models in R. It is mid-modernisation: since 2.12.0 cut the sp stack, each release has renamed part of the public surface, standardised how external packages attach custom mappers, or replaced internal machinery. 2.15.0 is the latest step, pairing a new predictor evaluation and linearisation implementation with broom's tidy(), glance() and augment() methods and four non-zero-truncated observation families.

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.

◆ Current state

inlabru wraps INLA for spatial, point-process and latent-Gaussian models in R. It is mid-modernisation: since 2.12.0 cut the sp stack, each release has renamed part of the public surface, standardised how external packages attach custom mappers, or replaced internal machinery. 2.15.0 is the latest step, pairing a new predictor evaluation and linearisation implementation with broom's tidy(), glance() and augment() methods and four non-zero-truncated observation families.

◆ Where it's heading

The arc is consolidation of the extension surface rather than expansion of the model catalogue. Every release adds mappers or families with one hand and removes a dependency, a re-export or a deprecated path with the other — plyr in 2.15.0, fmesher's Depends entry in 2.14.1, sp and ggmap in 2.12.0. The compatibility flag bru_compat_pre_2_14_enable and the temporary fm_int/fm_pixels re-exports show a maintainer sequencing breaks across releases instead of landing them together.

◆ Prediction

The 2.14 compatibility flag is still defaulting to TRUE and the fmesher re-exports are described in the entries as temporary, so the next obvious move is a release that flips bru_compat_pre_2_14_enable off and drops those re-exports.

0.0

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.
