timbr 0.3.0.9000
- New "Introduction to timbr" article on the package website walks through creating forests, hierarchical aggregation, combining forests, and
traverse().
timbr 0.3.0 (2026-07-16)
- Fixed a bug where forests with grouped root nodes (e.g. those produced by
summarise()) could error or behave incorrectly in downstream operations.
children() now gives a clear tidyselect error when a forest's root nodes don't share a single node name, instead of an internal assertion failure.climb()'s .deep argument has been renamed to .recurse (.deep is now deprecated), and a recursion bug that could corrupt node bookkeeping when climbing multiple levels has been fixed (#9).leaves() now correctly returns forests where every node is both root and leaf (e.g. single-level trees), instead of erroring.map_forest() is now defunct and throws an error; use traverse() instead (it has been deprecated since timbr 0.2.2).relocate() is now implemented for forests, moving columns while preserving the tree structure.rows_patch() and rows_update() are now implemented for forests, with fixes to by-column matching and error messages (#20).select() for forests now always preserves the internal node column, so selecting feature columns no longer breaks the tree structure.
timbr 0.2.2 (2023-04-29)
- Rename
map_forest() to traverse and deprecate map_forest().
- Update behavior of
as_tbl_graph.forest().
- Update deprecated functions in vctrs.
timbr 0.2.1 (2023-04-07)
- Rename the argument for
rowwise.forest().
- Fix problems with CRAN checks.
timbr 0.2.0 (2023-03-04)
- Now, display the tree structure in the header of
forest.
- Fix problems with CRAN checks.
timbr 0.1.1 (2022-09-19)
- Rename modify.forest() to map_forest() because modify() will no longer be S3
generics in purrr 1.0.0 (#1).
