glydraw vs gps2gtfs
A side-by-side editorial comparison of glydraw and gps2gtfs — release velocity, themes, recent moves, and the top alternatives to consider.
glydraw vs gps2gtfs: at a glance
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 gps2gtfs?
gps2gtfs spent a release making its docs stop describing functions it does not have.
gps2gtfs converts raw GPS traces into GTFS transit feeds, with a Rust backend behind the R interface. The only entry on record is 0.3.2, an explicitly documentation-only release: the trip extraction functions stop claiming to read CSV files when their own parameter docs always said data.frame or path, the bundled stop and terminal datasets state their Kandy, Sri Lanka provenance, and titles are normalized to sentence case.

◆ 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.
gps2gtfs
2.5ANALYTICS
gps2gtfs spent a release making its docs stop describing functions it does not have.
◆ Current state
gps2gtfs converts raw GPS traces into GTFS transit feeds, with a Rust backend behind the R interface. The only entry on record is 0.3.2, an explicitly documentation-only release: the trip extraction functions stop claiming to read CSV files when their own parameter docs always said data.frame or path, the bundled stop and terminal datasets state their Kandy, Sri Lanka provenance, and titles are normalized to sentence case.
◆ Where it's heading
One entry is not a trend, but the release is unusually precise about its own boundaries, stating outright that no behavior, signature, or return value changed and citing 533 passing tests from a clean detached clone with the specific CI job numbers. That level of provenance in a documentation patch suggests a maintainer treating the package as something others audit.
◆ Prediction
There is not enough history here to predict a direction. The Rust backend is the notable structural detail, and whether it expands is the question the next release will answer.
