The purpose of this R package is to standardize population sample size before comparing allelic richness (Â) estimates among different populations. The problem of unequal sample size is typical in clonal species where G, the number of different genotypes or genetic individuals, is the relevant statistic to standardize. Independently of the sample design used for clonal organisms G is unpredictable at that stage, even when N, the number of sample units, is kept constant across populations. Graphical functions are also available to; 1) plot allele distribution and frequency across populations for each locus, and 2) plot the relationship between allelic richness and genet/individual number in a population.
