write_bed: write_bed

Description

This function writes genotype information into a binary PED (BED) filed used in plink. For more details about this format see http://pngu.mgh.harvard.edu/~purcell/plink/binary.shtml.

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"
1
01 Heterozygote
2
10 Missing genotype
3
11 Homozygote "2"/"2"
