What is spsurvey?

spsurvey has spent four years consolidating after its 5.0.0 rewrite rather than adding to it

spsurvey implements design and analysis for spatially balanced environmental survey samples, the GRTS methodology used in large-scale monitoring programs. The 5.0.0 rewrite is the defining event in its history, and everything in this window is aftercare. 5.6.0 in September 2025 finally removed the startup message warning users about that upgrade, several years on.

What is timbr?

Three years dormant, timbr returns with dplyr verbs that finally respect tree structure

timbr provides a 'forest' class for nested tree data in R, letting users navigate parent/child relationships with tidyverse-style verbs. After its last release in May 2023, the package sat untouched for over three years before 0.3.0 landed in July 2026. That release is dominated by correctness work on the structural invariants that everything else depends on.

spsurvey has spent four years consolidating after its 5.0.0 rewrite rather than adding to it

◆ Current state

spsurvey implements design and analysis for spatially balanced environmental survey samples, the GRTS methodology used in large-scale monitoring programs. The 5.0.0 rewrite is the defining event in its history, and everything in this window is aftercare. 5.6.0 in September 2025 finally removed the startup message warning users about that upgrade, several years on.

◆ Where it's heading

The direction is toward standard R idioms and away from bespoke ones. 5.4.0 introduced sp_frame and sp_design classes so plot() and summary() work directly, keeping sp_plot() and sp_summary() only for backwards compatibility; 5.5.0 moved warnings from cat() to message() so they can be suppressed normally, and added adjwgtNR() for non-response weight adjustment. Documentation is being pushed off CRAN onto the package website, with only the Start Here vignette remaining. Release cadence is slow — five releases across roughly four years.

◆ Prediction

With the migration messaging retired and the class system settled, further releases are likely to stay in maintenance and statistical-detail territory. Nothing in the entries suggests another rewrite.

Three years dormant, timbr returns with dplyr verbs that finally respect tree structure

◆ Current state

timbr provides a 'forest' class for nested tree data in R, letting users navigate parent/child relationships with tidyverse-style verbs. After its last release in May 2023, the package sat untouched for over three years before 0.3.0 landed in July 2026. That release is dominated by correctness work on the structural invariants that everything else depends on.

◆ Where it's heading

The arc is from a working prototype toward a class that behaves correctly under the full dplyr surface. 0.3.0 implements relocate(), rows_patch() and rows_update() for forests and makes select() always preserve the internal node column, closing the gaps where a standard verb would silently break the tree. The deprecation of map_forest() in favour of traverse(), begun in 0.2.2, is now complete.

◆ Prediction

With the verb coverage gaps closed and the long deprecation cycle finished, the next release is likely to extend dplyr method coverage further rather than change the forest model. The entries do not indicate what prompted the three-year gap, so the sustainability of this cadence is unclear.
