I'd like to fit a non linear model using weighted least squares. I am using the gnls function but I don't know how to perform a weighted least squares (my weights are a "simple" colum of data).
In your case it probably would be easier to use nls (in stats) instead of gnls. There is an example using weighting on the help-page. Dieter Menne
