write_bed
This function writes genotype information into a binary PED (BED) filed used in plink. For more details about this format see http://zzz.bwh.harvard.edu/plink/binary.shtml.
write_bed(x,n,p,bed_file)
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. |
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" |
