In zhengxwen/HIBAG: HLA Genotype Imputation with Attribute Bagging

Conversion between the in-memory model and the object that can be saved in a file

Description

Build a model hlaAttrBagClass from an object of hlaAttrBagObj which is stored in an R object file, or convert hlaAttrBagClass to hlaAttrBagObj.

Usage

hlaModelFromObj(obj)
hlaModelToObj(model)

Arguments

obj	an object of hlaAttrBagObj
model	an object of hlaAttrBagClass

Value

hlaModelFromObj returns hlaAttrBagClass, and hlaModelToObj returns hlaAttrBagObj.

Examples

# make a "hlaAlleleClass" object
hla.id <- "DQB1"
hla <- hlaAllele(HLA_Type_Table$sample.id,
    H1 = HLA_Type_Table[, paste(hla.id, ".1", sep="")],
    H2 = HLA_Type_Table[, paste(hla.id, ".2", sep="")],
    locus=hla.id, assembly="hg19")

# training genotypes
region <- 100   # kb
snpid <- hlaFlankingSNP(HapMap_CEU_Geno$snp.id, HapMap_CEU_Geno$snp.position,
    hla.id, region*1000, assembly="hg19")
train.geno <- hlaGenoSubset(HapMap_CEU_Geno,
    snp.sel = match(snpid, HapMap_CEU_Geno$snp.id))

# train a HIBAG model
set.seed(1000)
model <- hlaAttrBagging(hla, train.geno, nclassifier=2)
print(model)

mobj <- hlaModelToObj(model)

is(model)
is(mobj)


# close the HIBAG model explicitly
hlaClose(model)
