a dataframe of genotype data with rownames of sample ID and column names of markers.
sep
allele separator in the imported genotype data. Note: when using the special character like "|", remember to protect it as "\|"(default).
expect
a logic variable. If expect is true, the function will calculate the expected genotype probabilities. If false, calculate the observed genotype frequencies.
Value
a dataframe of genotype frequencies. Each row denotes each genotype; each column denotes each loci. The order of markers follows x; the genotypes are ordered from homozygous to heterozygous.
Details
This function calculates the observed or expected genotype frequency from dataset and allele frequency.#####
