What is glydraw?

SNFG glycan cartoons stopped being pictures and became ggplot2 geoms, guides and axis labels.

glydraw renders glycan structures as SNFG-standard cartoons, standalone or exported in bulk, and since 0.7.0 as native ggplot2 components: geom_glycan() for observations, geom_node_glycan() for ggraph networks, guide_glycan() for legends, and scale_x_glycan() and scale_y_glycan() for discrete axes. Appearance is configured through a single reusable style object rather than scattered arguments, a consolidation that 0.8.0 made breaking. The colour handling now expects a complete SNFG palette rather than sparse per-monosaccharide overrides.

What is pedtools?

pedtools rewrote loop breaking and made a class of pedigrees analyzable for the first time.

pedtools is the foundation of the ped suite, holding the pedigree data structures every other package builds on. Version 2.11.0 revamped the loop breaking algorithm so founders can serve as loop breakers and one individual can break several loops, which makes likelihood calculations possible in pedigrees that previously could not be handled at all. Loop detection also became mandatory and faster, and the surrounding releases have steadily added query and construction helpers.

SNFG glycan cartoons stopped being pictures and became ggplot2 geoms, guides and axis labels.

◆ Current state

glydraw renders glycan structures as SNFG-standard cartoons, standalone or exported in bulk, and since 0.7.0 as native ggplot2 components: geom_glycan() for observations, geom_node_glycan() for ggraph networks, guide_glycan() for legends, and scale_x_glycan() and scale_y_glycan() for discrete axes. Appearance is configured through a single reusable style object rather than scattered arguments, a consolidation that 0.8.0 made breaking. The colour handling now expects a complete SNFG palette rather than sparse per-monosaccharide overrides.

◆ Where it's heading

The first half of this record is geometry correctness, fixing branch spacing, overlapping linkage annotations, core fucose collisions, triangle alignment and nested side-chain layout, because a cartoon that draws the wrong topology is worse than no cartoon. Once the drawing was trustworthy the package moved outward into ggplot2 and then inward again to consolidate its own API, dropping the glyexp dependency, removing positional argument support, and folding rendering options into style_glydraw(). Each of the last several releases has been explicitly breaking, which is a maintainer using a pre-1.0 window deliberately.

◆ Prediction

With the style object established and the ggplot2 surface in place, the remaining explicit arguments, show_linkage and orient, are the visible inconsistency and may follow the others into the style. Sibling packages adopt each change within days, as glyenzy did with the new orientation values, so expect the next breaking change to propagate the same way.

0.0

pedtools rewrote loop breaking and made a class of pedigrees analyzable for the first time.

◆ Current state

pedtools is the foundation of the ped suite, holding the pedigree data structures every other package builds on. Version 2.11.0 revamped the loop breaking algorithm so founders can serve as loop breakers and one individual can break several loops, which makes likelihood calculations possible in pedigrees that previously could not be handled at all. Loop detection also became mandatory and faster, and the surrounding releases have steadily added query and construction helpers.

◆ Where it's heading

The package has been working toward this for over a year. Version 2.8.0 replaced the igraph-based loop breaker with a custom implementation, 2.8.1 made findLoopBreakers() substantially faster in large pedigrees, and 2.11.0 rewrote the algorithm outright. The new methods ship disabled by default while downstream packages catch up, which is a deliberately staged rollout rather than a flag day. Alongside that, the additive work is small, well-scoped helpers: children2(), addSibling(), isHomozygous(), trim(), nChildren().

◆ Prediction

Expect the new loop breaking methods to become the default once pedprobr, forrel, and dvir have all shipped support for them, since the only stated reason for the opt-in flag is downstream readiness.
