What is mmpca?

Back from CRAN removal under a new maintainer, with the compiled layer rebuilt.

mmpca implements multiple matrix principal component analysis with a compiled GSL backend. The package spent time off CRAN, and its recent history is a rescue operation rather than a feature program: a new maintainer took it over, moved the native build path onto RcppGSL, and folded the hand-written C bindings into Rcpp. The two most recent entries landed the same day, one restoring the package and one clearing residual CRAN comments.

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.

Back from CRAN removal under a new maintainer, with the compiled layer rebuilt.

◆ Current state

mmpca implements multiple matrix principal component analysis with a compiled GSL backend. The package spent time off CRAN, and its recent history is a rescue operation rather than a feature program: a new maintainer took it over, moved the native build path onto RcppGSL, and folded the hand-written C bindings into Rcpp. The two most recent entries landed the same day, one restoring the package and one clearing residual CRAN comments.

◆ Where it's heading

Work is concentrated on making the package installable and check-clean rather than on the decomposition itself. The version stamps run out of order, with 2.0.3 predating both 2.0.2 and 2.0.4 by three years, so the feed reads as an archive flush around the CRAN return. Nothing in the entries points at method-level work.

◆ Prediction

Expect maintenance releases that keep the compiled code passing CRAN checks; the entries give no signal about new decomposition features.

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.
