adding values to ggplot legend

p<-ggplot(d,aes(Method, Prevalence, size=N))
p+geom_point()+ylab("% Prevalence Rate")+ labs(size = "# of Cases")

When creating this scatter-plot that has been weighted by N (continuous variable ranges from 0-300), I get a legend that displays the markers for N values 100, 200, 300 only. How do I add other values to this legend? Say add N=50 marker for this legend?
