hlaGenoCombine: Combine two genotypic data sets into one

In zhengxwen/HIBAG: HLA Genotype Imputation with Attribute Bagging

Combine two genotypic data sets into one

Description

To combine two genotypic data sets into one dataset.

Usage

hlaGenoCombine(geno1, geno2,
    match.type=c("Position", "Pos+Allele", "RefSNP+Position", "RefSNP"),
    allele.check=TRUE, same.strand=FALSE, verbose=TRUE)

Arguments

geno1	the first genotype object of hlaSNPGenoClass
geno2	the second genotype object of hlaSNPGenoClass
match.type	"RefSNP+Position" (by default) – using both of RefSNP IDs and positions; "RefSNP" – using RefSNP IDs only; "Position" – using positions only
allele.check	if TRUE, call hlaGenoSwitchStrand to check and then switch allele pairs if needed
same.strand	TRUE assuming alleles are on the same strand (e.g., forward strand); otherwise, FALSE not assuming whether on the same strand or not
verbose	show information, if TRUE

Details

The function merges two SNP dataset geno1 and geno2, and returns a SNP dataset consisting of the SNP intersect between geno1 and geno2, and having the same SNP information (allele and position) as geno1.

Value

An object of hlaSNPGenoClass.

Examples

# import a PLINK BED file
bed.fn <- system.file("extdata", "HapMap_CEU.bed", package="HIBAG")
fam.fn <- system.file("extdata", "HapMap_CEU.fam", package="HIBAG")
bim.fn <- system.file("extdata", "HapMap_CEU.bim", package="HIBAG")
hapmap.ceu <- hlaBED2Geno(bed.fn, fam.fn, bim.fn, assembly="hg19")

# combine two datasets together
geno <- hlaGenoCombine(HapMap_CEU_Geno, hapmap.ceu)
