rjwsacruncher vs tidytransit: at a glance
What is rjwsacruncher?
A thin R wrapper around a Java seasonal-adjustment tool, slowly absorbing the setup work.
rjwsacruncher drives JDemetra+'s JWSACruncher from R, handling parameter files and batch runs of seasonal adjustment workspaces. Recent releases have shifted from wrapping the executable to managing its installation: 0.2.3 adds a downloader for JDemetra+ itself, a check that a given directory really contains the cruncher binary, and tolerance for users pointing at the executable instead of its bin directory.
What is tidytransit?
tidytransit tracks the GTFS spec as it grows, one reader and one router feature at a time.
tidytransit reads GTFS transit feeds into tidy data frames and computes travel times using a RAPTOR implementation. Recent work splits between the reader keeping pace with the spec — locations.geojson in 1.7.0, empty strings parsed as NA in 1.8.0 — and the router gaining realism, most recently in-seat transfers. Feed specifications are now pulled from the automatically parsed GTFS reference rather than maintained by hand.

A thin R wrapper around a Java seasonal-adjustment tool, slowly absorbing the setup work.
◆ Current state
rjwsacruncher drives JDemetra+'s JWSACruncher from R, handling parameter files and batch runs of seasonal adjustment workspaces. Recent releases have shifted from wrapping the executable to managing its installation: 0.2.3 adds a downloader for JDemetra+ itself, a check that a given directory really contains the cruncher binary, and tolerance for users pointing at the executable instead of its bin directory.
◆ Where it's heading
The work is defensive. Most of each release addresses a way users misconfigure paths or versions — clearer errors, a startup message naming which cruncher version the options select, and a standalone flag on the downloader. The package is absorbing the friction of a Java dependency it does not control.
◆ Prediction
Expect continued compatibility work as JDemetra+ 3.x diverges from 2.x, since the version split is already surfaced as a user-facing option rather than resolved internally.
tidytransit
0.0ANALYTICS
tidytransit tracks the GTFS spec as it grows, one reader and one router feature at a time.
◆ Current state
tidytransit reads GTFS transit feeds into tidy data frames and computes travel times using a RAPTOR implementation. Recent work splits between the reader keeping pace with the spec — locations.geojson in 1.7.0, empty strings parsed as NA in 1.8.0 — and the router gaining realism, most recently in-seat transfers. Feed specifications are now pulled from the automatically parsed GTFS reference rather than maintained by hand.
◆ Where it's heading
The package has settled into tracking an external standard, which is why the changelog reads as a sequence of spec conformance items rather than a roadmap. Parsing responsibility keeps shifting outward to gtfsio, and data sources have moved with the ecosystem, from the retired transitfeeds API to MobilityData. Router changes are rarer than reader changes but land in the same releases.
◆ Prediction
Further GTFS spec features are the safest expectation, with GTFS-Flex the likeliest area now that locations.geojson reading is in place.
