[R-pkg-devel] What is a "retired"package?

[Jeff Newmiller]

There is nothing official about that term. However, the meaning as intended by the package authors seems pretty clear to me, and if some organization decides not to allow software that is not being maintained to be relied upon then that is their decision. I don't think slapping a different label on "I am not fixing this hot mess" is going to change that organization's stance, and expecting the author to play that game is unreasonable.

Welcome to the downside of package interdependencies. I highly recommend that you migrate away from plyr, either by absorbing the key functions you need from it or by relying on different packages.

There are no obvious replacements in purrr or dplyr, and if there were and I used them instead, it would increase my indirect dependencies to several packages that are not actually needed.

I did not find the term in "CRAN Repository Policy" or "Writing R Extensions." It appears that my user or their regulatory agency thinks it means that it could be deprecated in the near future. (If that is indeed what it means, there are 700+ packages in trouble!) Otherwise, perhaps the appropriate request may be to the plyr maintainers to modify how they describe its status, so as to avoid confusion.
