Apportionment of Quadratic Entropy
The hierarchical apportionment of quadratic entropy defined by Rao (1982).
apqe(samples, dis = NULL, structures) ## S3 method for class 'apqe' print(x, full = FALSE, ...)
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 |
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 |
full |
a logical value that indicates whether the original data ('distances', 'samples', 'structures') should be printed |
... |
|
Returns a list of class apqe
call |
call |
results |
a data frame that contains the components of diversity. |
