Examples

  ## Not run: 
  ## Simulate some allele frequencies:
  freqs <-  replicate(10, { g = rgamma(n=10,scale=4,shape=3); g/sum(g)},
              simplify=FALSE)
  ## Load the sample database:
  data(dbExample)
  obs <- dbCompare(dbExample,trace=FALSE)$m
  C3 <- optim.relatedness(obs,theta0=0.0,theta1=0.03,probs=freqs,
          objFunction='C3',max.bisect=30,trace=TRUE)
  plot(C3)
  
## End(Not run)
