Description

The function reads BED formatted files. The BED file format defined by UCSC: http://genome.ucsc.edu/FAQ/FAQformat. First three columns ("chrom", "chromStart", "chromEnd") are mandatory. The file fields may be separated by tabs, spaces or commas. If the BED file contains a header, it will be ignored. If a genome mask dataframe is provided, only data intersected with the mask will be retained. Resulting data is ordered by "chromStart" columns.
