‘R CMD check’ now handles archives with extension ‘.tar’ or ‘.tar.zstd’ (where ‘zstd’ compression is supported by the R build).
‘as.vector()’ gains a ‘data.frame’ method which returns a simple named list, also clearing a long-standing ‘FIXME’ to enable ‘as.vector(<data.frame>, mode="list")’. This breaks code relying on ‘as.vector(<data.frame>)’ to return the unchanged data frame.
