ieegio vs timbr: at a glance
What is ieegio?
ieegio's first release lands electrode trajectory burning and a WebGL-free surface plot
ieegio handles file I/O and volume manipulation for intracranial EEG and neuroimaging data in R. Only one release is on record, 0.1.0 from May 2026, so there is no cadence to read yet. Its content is a mix of new volume-authoring capability and format-level correctness fixes.
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.

ieegio's first release lands electrode trajectory burning and a WebGL-free surface plot
◆ Current state
ieegio handles file I/O and volume manipulation for intracranial EEG and neuroimaging data in R. Only one release is on record, 0.1.0 from May 2026, so there is no cadence to read yet. Its content is a mix of new volume-authoring capability and format-level correctness fixes.
◆ Where it's heading
The release points at two audiences at once: burn_curve() writes electrode trajectories — depth/sEEG leads, DBS shafts — into a volume from start and end positions in native RAS coordinates, with a merge mode so trajectories compost onto an existing volume rather than overwriting it. Separately, a base R graphics plot method for surfaces provides a path for environments without WebGL, where the default r3js renderer cannot run. Format work covers BCI2000 and BrainVision channel lookup by label and a quaternion handedness fix aligning with FreeSurfer conventions.
◆ Prediction
A single release gives no basis for predicting cadence. The FreeSurfer alignment and multi-format channel handling suggest interoperability with established neuroimaging toolchains is the near-term priority.

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.
