[R] Access Object's Objects HELP

[DivineSAAM@aol.com]

Dear WizaRds,

A run of nls produces the following concise summary:

> summary(cs.wt)

Formula: 0 ~ wt.MM(conc, time, A1, a1, A2, a2)

Parameters:
    Estimate Std. Error t value Pr(>|t|)  
A1 4.814e+02  2.240e+01  21.495   0.0296 *
a1 7.401e-01  7.435e-02   9.956   0.0637 .
A2 1.613e+02  1.738e+01   9.280   0.0683 .
a2 1.770e-02  7.324e-03   2.417   0.2497  

------------------------------------------
I need to access the estimates of A1,a1,A2...

How can I do this?

Also, I need to add a column to Parameters: giving
the ratio of the Std. Error to Estimate. Is there a way to get summary to do this?
I can't find the summary implementation.

I am using R 1.7.0 on Windows XP

HELP! Please:-)
