SSweibull

Dear Prof Ripley, 

there was no (direct) answer to any of my questions in your post, but
I think I'm getting the idea! Sorry for my ignorance.

And I still seem to have a gross misunderstanding about the use of
`SSweibull(nls)'. 

Is it simply a means to calculate the Weibull
distribution?  

What's the difference to `pweibull', then?  

Which means could help me estimating the Weibull parameters from
empirical data?

And what does it mean that `[SSweibull is] intended to be used by a
call to nls()'?

Thanks for your patience, Mirko.
