I was indicating two reasons why I wanted to be able to downgrade to 2.13.1 but I should have modified the subject.

However, that will be unnecessary since I now have perfectly good explanations for both issues, neither of which I would have figured out for myself.

It's so long since I set up the keep.source option I'd forgotten that's what I should have been searching for. |> |> This means that if you save a function under R 2.13.1 and |> load/attach it under R 2.14.0, its kept source (with the comments) |> is no longer available.
