Hi all, I'm smoothly transferring my lattice graphs to ggplot2 graphs, but I'm stuck on representing a curve from a formula. I'm looking for the equivalent of curve() in ggplot2, Hadley Wickham mentions geom_curve, but as far as I've seen in the help it doesn't exist. My need is to plot a regular scatter plot of experimental data (easy to do actually) and then add the fitting model according to a specific formula like y = a*(b*x^n)/(1+b*x^p) where a,b,n and p are known parameters. I guess it's possible and easy to add this layer with ggplot, somehow I didn't find the right function. Any help would be warmly appreciated.
