What is transltr?

A new R localization package that reached CRAN and immediately downgraded itself to experimental.

transltr is a young package for supporting many languages in R, built around Text and Translator classes. Its entire public history is four release candidates over four weeks in early 2025 — there are no final tags, so the RC is the release event here. Two of the four exist only to satisfy CRAN reviewers.

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.

A new R localization package that reached CRAN and immediately downgraded itself to experimental.

◆ Current state

transltr is a young package for supporting many languages in R, built around Text and Translator classes. Its entire public history is four release candidates over four weeks in early 2025 — there are no final tags, so the RC is the release event here. Two of the four exist only to satisfy CRAN reviewers.

◆ Where it's heading

The arc is unusually candid about instability. The first release shipped with an explicit instruction to treat it as beta until 1.0.0, and 0.1.0 then went further, reverting the package's lifecycle badge from a firmer status back to experimental because the maintainer had broken more than intended — naming the Text and Translator methods as the parts still likely to move. Test coverage is repeatedly cited as the thing holding the package together while the interface is not yet fixed.

◆ Prediction

The self-declared plan is a 1.0.0 that settles the Text and Translator method signatures; until then expect further breaking changes, and the release notes will most likely keep pointing at NEWS.md rather than summarising them.

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.
