hlaHaploSubset: Get a subset of haplotypes

In HIBAG: HIBAG -- HLA Genotype Imputation with Attribute Bagging

Description

To get a subset of haplotypes from a hlaSNPHaploClass object.

Usage

hlaHaploSubset(haploobj, samp.sel=NULL, snp.sel=NULL)

Arguments

haploobj	a haplotype object of hlaSNPHaploClass
samp.sel	a logical vector, or an integer vector of indices
snp.sel	a logical vector, or an integer vector of indices

Details

haploobj$haplotype is a numeric matrix, with an entry value 0 standing for B (ZERO A allele), 1 for A (ONE A allele) and others for missing values (missing genotypes are usually set to be NA).

Value

Return a hlaSNPHaploClass object, and it is a list:

haplotype	a haplotype matrix, “# of SNPs” - by - “2 x # of individuals”
sample.id	a vector of sample IDs
snp.id	a vector of SNP IDs
snp.position	a vector of SNP positions in basepair
snp.allele	a vector of characters with the format of “A allele/B allele”
