What is glyrepr?

The type system the rest of the glycan stack is built on, being hardened one breaking change at a time.

glyrepr defines the vector types for glycan structures and compositions that every sibling package operates on, with names, NA values, resolution levels from basic through intact, and mapping helpers over structure vectors. Structures now convert to and from node and edge tibbles, low-level constructors support name-preserving construction from trusted graphs, and as_glycan_structure() can degrade element-local failures to NA with one aggregated warning instead of failing the whole vector. The monosaccharide table has been normalised so every entry has a generic form, and substituent support keeps widening.

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.

The type system the rest of the glycan stack is built on, being hardened one breaking change at a time.

◆ Current state

glyrepr defines the vector types for glycan structures and compositions that every sibling package operates on, with names, NA values, resolution levels from basic through intact, and mapping helpers over structure vectors. Structures now convert to and from node and edge tibbles, low-level constructors support name-preserving construction from trusted graphs, and as_glycan_structure() can degrade element-local failures to NA with one aggregated warning instead of failing the whole vector. The monosaccharide table has been normalised so every entry has a generic form, and substituent support keeps widening.

◆ Where it's heading

This package sets the pace for the cohort, and its breaking changes show up as compatibility patches in glyanno, glyenzy and glymotif within days. The direction is toward behaving like a well-built vctrs type: 0.10.0 rewrote the internals to support names and NA properly, 0.11.0 made structure level a vector-wide scalar rather than a per-element value, and the recent releases keep making failure explicit rather than silent, with strict input checks and typed errors replacing quiet drops. Dependencies get shed as readily as features get added, with the parallel-mapping arguments and their furrr and future dependencies removed outright in 0.13.0.

◆ Prediction

The graph-table conversions added in 0.13.0 and the name-preserving low-level constructors in 0.14.0 both look like foundations for other packages to build structures programmatically, so expect that surface to firm up next. Given the cadence of breaking changes, a 1.0 that freezes the type semantics is the more consequential thing to watch for.

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.
