contagionchannels vs rapr: at a glance
What is contagionchannels?
Three releases in ten days, every one of them a CRAN reviewer's correction rather than a code change.
contagionchannels reached CRAN on 2026-05-08 with a methodology preprint behind it and a cross-quantilogram lineage visible in its citations. What the release feed does not contain is any description of what the package computes: all three entries document the submission process — a licence field reduced from GPL-3 plus file to plain GPL-3, an arXiv reference rewritten in canonical DOI form, and a base-graphics fallback adjusted on a reviewer's request.
What is rapr?
rapr generalises its Rangeland Analysis Platform API access one endpoint at a time
rapr pulls Rangeland Analysis Platform data into R — vegetation cover and production rasters derived from Landsat and Sentinel-2, plus the tabular summary APIs. The 1.1.3 release replaces the single-purpose table function with a general get_rap_table() covering the cover, coverMeteorology, production and production16day endpoints. The package reached CRAN in 2025 and is maintained by brownag, who also maintains the GeoPackage interface gpkg.

◆ Current state
contagionchannels reached CRAN on 2026-05-08 with a methodology preprint behind it and a cross-quantilogram lineage visible in its citations. What the release feed does not contain is any description of what the package computes: all three entries document the submission process — a licence field reduced from GPL-3 plus file to plain GPL-3, an arXiv reference rewritten in canonical DOI form, and a base-graphics fallback adjusted on a reviewer's request.
◆ Where it's heading
There is no product trajectory to read here yet, only a submission one, and it is unusually well documented — each entry names the reviewer or check that prompted it and quotes the feedback verbatim. That transparency is the one signal available: the maintainer treats review rounds as releases worth publishing rather than squashing. Any judgement about direction will have to wait for a release that changes the package rather than its metadata.
◆ Prediction
With CRAN acceptance secured, the next release should be the first to carry actual methodological content; until one appears, there is not enough in these entries to say where the package is heading.

rapr generalises its Rangeland Analysis Platform API access one endpoint at a time
◆ Current state
rapr pulls Rangeland Analysis Platform data into R — vegetation cover and production rasters derived from Landsat and Sentinel-2, plus the tabular summary APIs. The 1.1.3 release replaces the single-purpose table function with a general get_rap_table() covering the cover, coverMeteorology, production and production16day endpoints. The package reached CRAN in 2025 and is maintained by brownag, who also maintains the GeoPackage interface gpkg.
◆ Where it's heading
The shape is familiar for a young API client: add access to one endpoint, then generalise it once a second endpoint proves the pattern. get_rap_production16day_table() arrived in 1.1.0 and was deprecated three releases later in favour of a product argument. Between those, the work was error handling — empty geometries, server-side HTTP failures, warning timing — the unglamorous half of wrapping a remote service. The 1.0.0 release had already set the ambition by exposing both the 30m Landsat and 10m Sentinel-2 sources behind one argument.
◆ Prediction
Expect the remaining RAP endpoints to be folded into get_rap_table() as they are needed, and the deprecated 16-day function to be removed once the general interface has been out long enough.
