[R] Plotting a curve for a Holling Type III Functional Response

So I have a scatter plot and I am trying to plot a curve to fit the data
based on a Holling Type III functional response. My function is this:

nll2<-function(a,b) {
  nlls2<-dnbinom(x=cones ,size=DBH, mu=conefun,log=TRUE)

and my plot is this:

plot (DBH,cones)

DBH is on the x-axis and cones is on the y-axis. How do I get the curve for
my function onto the scatterplot?
