How can I get at the estimated parameter values from a non-linear model fitted by nls in R, so as to plot the fitted curve? If I have f.t <- nls(f~a*exp(b*t), ...) then type names(f.t), all that shows up is m for model, data, and call. I don't see how to get at a and b, other than to print them. Thanks.
