...ay to find sensible starting values is to plot the data, guess some parameter values, and superimpose the model curve using those values. The problem is that fn is not the model to be fitted. The model is y = p1*x/(p2 + x). The function fn is the function to be minimized. So I think the sendtence 'The model to be fitted is:' should be changed to 'The function to be minimized is:" or something like that.
