[R-sig-ME] nlme update query

[Cole, Tim]

I fit mixed effects models in nlme using my sitar package, and I am puzzled that some models which fitted fine at the start of November no longer converge. Nothing has changed at my end, which makes me wonder if nlme has altered its behaviour somehow � I did update it at one point.

Have there been any recent substantive changes to nlme?

Thanks,
Tim
