The hierarchical apportionment of quadratic entropy defined by Rao (1982).
Usage
apqe(samples, dis = NULL, structures)
# S3 method for apqe
print(x, full = FALSE, …)
Arguments
samples
a data frame with haplotypes (or genotypes) as rows, populations as columns
and abundance or presence-absence as entries
dis
an object of class dist computed from Euclidean distance.
If dis is null, equidistances are used.
structures
a data frame that contains, in the jth row and the kth column,
the name of the group of level k to which the jth population belongs
x
an object of class apqe
full
a logical value that indicates whether the original data ('distances', 'samples', 'structures')
should be printed
…
… further arguments passed to or from other methods
Value
Returns a list of class apqe
call

results
a data frame that contains the components of diversity.
