h.zygosity {rCNV} | R Documentation |
Determine per sample heterozygosity and inbreeding coefficient
Description
This function will calculate the heterozygosity on a per-sample basis from vcf files (snps), and most importantly inbreeding coefficient which is used to filter out the samples with bad mapping quality.
Usage
h.zygosity(vcf, plot = FALSE, pops = NA, verbose = TRUE)
Arguments
vcf |
an imported vcf file in in a list using
|
plot |
logical. Whether to plot a boxplot of inbreeding coefficients for populations. A list of populations must be provided |
pops |
character. A list of population names with the same length and order as the number of samples in the vcf |
verbose |
logical. Show progress |
Value
Returns a data frame of expected “E(Hom)” and observed “O(Hom)” homozygotes with their inbreeding coefficients.
