Examples

data(butterflies)

# First, estimate the probability of mutation:
nu <-
  optimize(f=theta.likelihood,interval=c(1,100),maximum=TRUE,give.log=TRUE,x=butterflies)$maximum
prob <- nu/(2*sum(butterflies))

#Now plot the dominance diversity curve:
species.curve(butterflies,pch=16,type="o",cex=3,col="red",lwd=3)

#Now plot simulated dominance diversity curves using the above estimation:
for(i in 1:10){
  jj <- untb(n=376,gens=1000,start.mono=TRUE, prob.of.mutate=prob)

  jj <- sort(table(jj),decreasing=TRUE)
  points(1:length(jj),jitter(jj),type="l")
}
