### Examples

    # Retrieve system files
    extdata.dir <- system.file("extdata", package="RIPSeeker")

    bamFiles <- list.files(extdata.dir, ".bam$", recursive=TRUE, full.names=TRUE)

    bamFiles <- grep("PRC2", bamFiles, value=TRUE)

    alignGal <- getAlignGal(bamFiles[1], reverseComplement=TRUE, genomeBuild="mm9")

    alignGR <- as(alignGal, "GRanges")

    alignGRList <- GRangesList(as.list(split(alignGR, seqnames(alignGR))))

    binSize <- 1e5  # use a large fixed bin size for demo only

    binGR <- binCount(alignGRList$chrX, binSize)

    # test on GRanges object
    nbhGR <- nbh(binGR, 2, runViterbi=TRUE)

    # test on integer object
    nbhList <- nbh(values(binGR)$count, 2, runViterbi=TRUE)
