human mitochondrial DNA restriction data
Description
This data set gives the frequencies of haplotypes of mitochondrial DNA restriction data in ten populations all over the world.
It gives also distances among the haplotypes.
Usage
data(humDNAm)
Format
humDNAm
is a list of 3 components.
- distances
is an object of class
dist
with 56 haplotypes. These distances are computed by counting the number of differences in restriction sites between two haplotypes.- samples
is a data frame with 56 haplotypes, 10 abundance variables (populations). These variables give the haplotype abundance in a given population.
- structures
is a data frame with 10 populations, 1 variable (classification). This variable gives the name of the continent in which a given population is located.
