# 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
# 388.8673
