starting values update

Hi all,
does anyone know how to automatically update starting values in R?

See ?set.seed

Off target, Uwe. This was about starting values for a nonlinear fit. 
More likely something about self-starting models is relevant here. 
There's a chapter in the 2nd edition of my book, but it doesn't quite go 
all the way to writing your own self-starting models. There's a brief 
outline and an example in some oldish course slides here:

(And please don't quote entire digests back to the list. It is 
potentially explosive...)

I' m fitting multiple nonlinear models and would like to know how I 
can update starting values without having to type them in.
thank all
