[R] Fitting arbitrary curve to 1D data with error bars

Dear R experts, I was wondering how I could do a fit (say minimum chi2) to a 1D data with error bars. I searched quite a lot on the web, found out about the fitdistr() function in MASS, etc., but none of the things I found gives what I am really looking for. Perhaps I do not exactly know the pr

Thanks, but if you have another closer look to my post, you will see that my question has nothing to do with drawing error bars on a plot. What I want is to do a curve fit to a data with error bars. Best, e. On 14 Nov 2013, at 04:21, Suzen, Mehmet wrote: > If you are after adding error bars in
