Access to calculations in nls
Hi,
I would like to be able to access the calculated results from the nls package.
Using the example in R, fm3DNase1 we can reurn certain parts of the
calculations:

Parameter info from nls object
Hi!
When checking validity of a model for a large number
of experimental data I thought it to be interesting
to check the information provided by
the summary method programmatically.
Still I could not find out which method to
use to get to those data.
Example (not my real world data, but to show the point):
[BEGIN]
> DNase1 <- subset(DNase, Run == 1)
> fm1DNase1 <- nls(density ~

Thank you very much for the example. I think interactively I could get
something.
But my obstacle is to write an R script that processes my set of data
automatically.
My difficulty is to extract the information that appears on the screen, when
R is operated interactively, from a scripts.
Let me go over some steps to make sure I am doing things right.
Assume my data have been read into the matrix

How can I extract information from list which class is nls
Hello!
I work with :
R : Copyright 2006, The R Foundation for
Statistical Computing

On Windows XP Professional (Version 2002) SP2.
At this moment I use the function "nls" combined
with a selfStar model (SSmicmen, related to
Michaelis-Menten equation, and provided by the
"stats" package).
When I realise the following operation (cf. p 59
