gps2gtfs vs pedmut: 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 pedmut?
pedmut turns awkward mutation models into ones the likelihood engine can actually handle.
pedmut builds and transforms the mutation models used in pedigree likelihood calculations. Its recent arc is a toolkit of model transformations: makeReversible() with three methods, makeStationary() replacing the older stabilize(), adjustRate() for tuning overall mutation rate, and lumpMutSpecial() for lumping models that strong lumpability cannot handle. The most recent release is narrow, adding a programmatic output format to getParams().

◆ 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.
pedmut
0.0ANALYTICS
pedmut turns awkward mutation models into ones the likelihood engine can actually handle.
◆ Current state
pedmut builds and transforms the mutation models used in pedigree likelihood calculations. Its recent arc is a toolkit of model transformations: makeReversible() with three methods, makeStationary() replacing the older stabilize(), adjustRate() for tuning overall mutation rate, and lumpMutSpecial() for lumping models that strong lumpability cannot handle. The most recent release is narrow, adding a programmatic output format to getParams().
◆ Where it's heading
The consistent goal is making models satisfy the mathematical properties downstream algorithms require. Reversibility, stationarity, and lumpability each unlock something in pedprobr, and the package keeps adding ways to coerce an arbitrary model into having them. lumpMutSpecial() is explicitly incomplete, described as covering only some cases with more possibly to follow, which sets up the main open thread.
◆ Prediction
Expect additional special lumping cases to be implemented, since the package documents the current coverage as partial and pedprobr's likelihood performance depends directly on it.
