I don't know the answer to your question.
However, here's a side issue that may be relevant.
Last year, I tried creating my own ecdf object, and redefined the print
method for ecdf.
It worked ok in the console, interactively.
However, when I tried calling the method (with autoprinting) inside an
Sweave document, the stats package method was used instead of my method.
I never determined why this was happening.
However, R check generated a warning later, so I renamed the classes and
methods.
