In andremrsantos/htspop: High-Troughput Sequencing Population Genetics Statistics

htspop

Overview

htspop is a R package designed for analysis and computation of population genetic statistics using high-dimensional biallelic data. It includes the following statistics:

• Reich's f2, f3, and f4 statistics, similar to treemix implementation.
• Patterson's D statistics (also known ABBA/BABA test).
• jackknife mean estimator.
• Reich, Weir & Cockerham, Hudson, and Wright Fst and their bootstrap estimation.
• Nei's standard and Da genetic distance and a bootstrap estimator.

Instalation

You may install the development version, using devtools

# devtools instalation
devtools::install_github("andremrsantos/htspop")

Usage

## Simulate genotype matrix
geno <- matrix(sample(0:2, 100, replace = TRUE), ncol = 10)
## Convert into Allele Count structure
ac <- ac_matrix_from_genotype(geno) 
## Run F Statistics
jackknife(f4_stat(ac, c(1, 2, 3, 4)))
jackknife(f3_stat(ac, c(1, 2, 3)))
## Run D Statistics
jackknife(d_stat(ac, c(1, 2, 3, 4)))
## Compute Weir & Cockerham Fst and Nei Standard Genetic Distance
fst(ac, "wc")
nei(ac)
