Hi everyone,

 I am using nls() to run a simple sigmoid curve type of regression and
would like to see how the parameter values change through iterations. How
can I see those values? Or ideally, can I even extract those values?

For example,

nls(Response~E0+Emax*Conc/(EC50+Conc), data=data, start=list(....))

I would like to see how Emax and EC50 values change through iterations.
Thanks.
