### Examples

    # Load data
    data(nucleosome_htseq)
    cover <- coverage.rpm(nucleosome_htseq)

    # Create wig file
    export.wig(cover, name="example_track")

    # This would create the file "example_track.chr1.wig" with:

    # track type=wiggle_0 name="example_track"
    # fixedStep chrom=chr1 start=1 step=1
    # 55.55247
    # 55.55247
    # 55.55247
    # 277.7623
