R help - Jan 2005 - Help in Customising NLS function to spit out Mean and SD of the new fit!!!

Hi all,
 I'm trying to customize the nls function code to spit out the sd and mean
of the new fit. All it gives me are the fitted values. THis function seems to
work fine for my project otherwise. All i need is the SD and MEAN. Can someone
help me to customise. I frankly did not understand the nls code at all.
 
I have 10 x and 10 y values from a histogram. I need to use nls to do the best
fit and give me the mean and sd of this new fit.
 
Thanks in advance

I'm very sorry, but I don't understand what you did and what you 
don't understand.  Have you worked through the examples in the
"nls"
documentation?  If you have and still have questions, "PLEASE do read 
the posting guide! http://www.R-project.org/posting-guide.html".  In 
particular, please provide a very brief and simple, self contained 
example, so someone can copy a few lines from your email and paste it 
into R to replicate what you got.  With that, you will more likely get a 
useful answer.  

      hope this helps.
