[R-sig-ME] nlme issue

[Thierry Onkelinx]

Dear Raymond,

I would recommend to contact the maintainers of those packages. Maybe
something changed in nlme and did not percolate into those packages.

Best regards,

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of data.
~ John Tukey
