What is campsis?

Campsis breaks its API on purpose: snake_case throughout, RxODE compatibility cut loose.

Campsis runs clinical-trial simulations from pharmacometric models, sitting on mrgsolve and rxode2 as interchangeable engines, with the sibling package Campsismod supplying the model object layer. Version 1.9.0 is the release where the suite stops carrying its history: the whole API migrates to snake_case, backward compatibility with the old RxODE package is removed, and result processing is refactored into output functions that can be applied as a collection, with an NCA table the first substantial one. Campsismod made the same snake_case move a week earlier, so this is a suite-wide rename rather than one package's decision.

What is valr?

valr's interval verbs now read genomic files in place instead of demanding a loaded tibble.

valr reimplements bedtools-style genome interval arithmetic as tidyverse verbs backed by C++. Its long project has been closing the behavioural gap with bedtools — the book-ended interval semantics finally match in 0.10.0, three releases after the deprecation began. The July release also ends the assumption that intervals must be in memory: bed_map(), bed_intersect(), bed_subtract(), bed_coverage() and bed_window() accept a bigWig or bigBed path or URL where an interval table used to go.

Campsis breaks its API on purpose: snake_case throughout, RxODE compatibility cut loose.

◆ Current state

Campsis runs clinical-trial simulations from pharmacometric models, sitting on mrgsolve and rxode2 as interchangeable engines, with the sibling package Campsismod supplying the model object layer. Version 1.9.0 is the release where the suite stops carrying its history: the whole API migrates to snake_case, backward compatibility with the old RxODE package is removed, and result processing is refactored into output functions that can be applied as a collection, with an NCA table the first substantial one. Campsismod made the same snake_case move a week earlier, so this is a suite-wide rename rather than one package's decision.

◆ Where it's heading

The 1.8 and 1.9 releases together describe a package being made drivable from outside R. JSON interfaces arrived first for models in Campsismod 1.3.0 and for datasets in Campsis 1.8.0, then extended to scenarios, settings and study replication; the output side has now been generalised the same way, from fixed result processing to a collection of output functions applied to simulated results. Renaming every function and cutting RxODE loose is the cost of that consolidation, paid in one deliberate breaking release rather than spread across several.

◆ Prediction

With the rename and the RxODE removal behind it, the next releases should restore the rxode2 engine to the test suite, which 1.9.0 removed temporarily, and continue filling out the output-function catalogue beyond NCA. The JSON surface looks like the intended entry point for driving Campsis from outside R, though the entries do not say what is meant to consume it.

valr's interval verbs now read genomic files in place instead of demanding a loaded tibble.

◆ Current state

valr reimplements bedtools-style genome interval arithmetic as tidyverse verbs backed by C++. Its long project has been closing the behavioural gap with bedtools — the book-ended interval semantics finally match in 0.10.0, three releases after the deprecation began. The July release also ends the assumption that intervals must be in memory: bed_map(), bed_intersect(), bed_subtract(), bed_coverage() and bed_window() accept a bigWig or bigBed path or URL where an interval table used to go.

◆ Where it's heading

Two arcs converge here. One is compatibility: min_overlap arrived with a deprecation warning in 0.9.0 and its default flipped from 0 to 1 in 0.10.0, so book-ended intervals are excluded by default as bedtools does, with the internal calculations in bed_closest() and friends deliberately left counting them. The other is the file-backed path, which grew out of the cpp11bigwig dependency adopted in 0.8.3 for read_bigwig() and re-exported in 0.9.0 — reading a file became querying one. Underneath, the C++ base keeps getting lighter: Rcpp swapped for cpp11, rlang cut to a single function, per-group memory copies removed from three verbs.

◆ Prediction

Only five verbs take a file argument today and bed_closest(), bed_glyph() and the statistical verbs do not, so extending the file-backed path across the rest of the API is the obvious follow-up. The deprecated tibble re-exports and the now-defunct n_fields argument suggest continued removal of the compatibility layer in the next minor release.
