R Project Updates

Updates from R Core:

  • All packages are by default byte-compiled on installation. This makes the installed packages larger (usually marginally so) and may affect the format of messages and tracebacks (which often exclude .Call and similar).

  • The "Date" and “date-time” classes "POSIXlt" and "POSIXct" now have a working length<- method, as wished in PR#17387.

  • R has new serialization format (version 3) which supports custom serialization of ALTREP framework objects. These objects can still be serialized in format 2, but less efficiently. Serialization format 3 also records the current native encoding of unflagged strings and converts them when de-serialized in R running under different native encoding. Format 3 comes with new serialization magic numbers (RDA3, RDB3, RDX3). Format 3 can be selected by version = 3 in save(), serialize() and saveRDS(), but format 2 remains the default for all serialization and saving of the workspace. Serialized data in format 3 cannot be read in R prior to version 3.5.0.

  • Using \usage{ data(<name>, package="<pkg>") } no longer produces R CMD check warnings.
