Usage

  write_bed(x,n,p,bed_file)

Arguments

n	integer, number of individuals.
p	integer, number of SNPs.
x	integer vector that contains the genotypic information coded as 0,1,2 and 3 (see details below). The information must be in snp major order. The vector should be of dimension n*p with the snps stacked.
bed_file	output binary file with genotype information.

Details

The vector contains integer codes:

Integer code	Genotype
0	00 Homozygote "1"/"1"
