chaoHaplo: Chao estimator of haplotype number

Description

Calculates the Chao1 estimate of the number of haplotypes in a population based on the total number of haplotypes present, and the number of singletons and doubletons in the dataset.

Usage

chaoHaplo(DNAbin)

Value

An vector of length three, giving the estimated total number of haplotypes in the population, and lower and upper 95% confidence limits.

Arguments

DNAbin

An object of class `DNAbin'.

Details

The function assumes a large number of specimens have been sampled and that duplicate haplotypes have not been removed. Interpretation becomes difficult when more than one species is included in the dataset.
