get.freq: Calculate the gene(allele) frequency
In beibeiJ/SimPhe: Tools to Simulate Phenotype(s) with Epistatic Interaction

Description Usage Arguments Value Author(s) Examples

Calculate the gene(allele) frequency for each of the SNPs.

1	get.freq(geno, epi.pars, ...)

`geno`	a dataframe of genotype data: columns are the SNPs; lines are indviduals.
`epi.pars`	a data.frame or a matrix containing the parameter information for epistatic effect: additive * additive, additive * dominance, dominance * additive, and dominance * dominance.
`...`	not used

a dataframe with allele frequencies (major and minor).
