This blog is updated daily.
A general description is here.
The translations have been updated by the R Translation Team, with the patch generated by Gergely Daroczi. This includes a major contribution of over 4000 Arabic translations from Abdulrahman Alswaji.
‘tools::add_datalist()’ now returns a logical (invisibly, instead of ‘NULL’), indicating if it did add a ‘data/datalist’ file (addressing parts of PR#18015).
‘R CMD build’ now excludes an obsolete ‘data/datalist’ file when the package uses ‘LazyData’, and reports when it added one.
‘lm(.., weights = *)’ gets a new optional argument ‘wtol’, defaulting to 0 currently for back compatibility. Setting ‘wtol = 1e-30’ fixes PR#17475 thanks to the ‘R Dev Day’ 2025 participants Kelly Bodwin et al.
Atypical ‘lm()’ calls now work better, e.g., ‘fm <- lm(rock); update(fm, . ~ . - perm)’ and similar cases, fixing PR#17463 and PR#17476 and part of PR#1861, thanks to Ben Tyner, Elin Waring, Kevin Tappe and other bugzilla contributors.
‘pkg2HTML(dir="pkg")’ and other ‘tools’ consuming the ‘Rd_db()’ of a source package, e.g., the ‘undoc()’ QC function (PR#18960, thanks to Michael Chirico), no longer fail from processing ‘DESCRIPTION’-based Rd macros such as \packageTitle when the current directory is not the source package's root directory.
