hlaModelFromObj {HIBAG} | R Documentation

## 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)
