[R] predict.nls confidence intervals

[Prof Brian Ripley]

It is _just two days_ since someone asked:

https://stat.ethz.ch/pipermail/r-help/2006-April/092437.html

and that question was answered several times in the recent past, so I at 
least declined to answer it again.

A quick search via RSiteSearch() shows several explanations

and even an (approximate) solution

If non-linearity matters, simulation can be very effective.
