gps2gtfs vs pedFamilias: at a glance
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.
What is pedFamilias?
pedFamilias exists to read one legacy file format, and it has that job nearly finished.
pedFamilias holds the Familias file interoperability code that was split out of forrel, principally readFam() and writeFam(). The visible history is short and narrow: URL paths accepted as input, a deduplicate option for files produced by the Familias DVI module, better handling of extra individuals, and a fallback mutation model when stabilization fails. The most recent release is explicitly maintenance.

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.
pedFamilias
0.0ANALYTICS
pedFamilias exists to read one legacy file format, and it has that job nearly finished.
◆ Current state
pedFamilias holds the Familias file interoperability code that was split out of forrel, principally readFam() and writeFam(). The visible history is short and narrow: URL paths accepted as input, a deduplicate option for files produced by the Familias DVI module, better handling of extra individuals, and a fallback mutation model when stabilization fails. The most recent release is explicitly maintenance.
◆ Where it's heading
This is a package with a bounded remit. The format it parses does not change, so releases arrive only when someone encounters a file it mishandles, and the fixes are correspondingly specific. The interesting movement is upstream instead: forrel finally removed its deprecated readFam() re-export in 1.9.0, completing the split that created this package.
◆ Prediction
Expect continued low-frequency maintenance driven by real-world .fam files rather than any planned feature work.
