Illustration of key bedr operations. bedr regions objects represent a collection of sub-regions specified as R vector or data.frame. Three partially overlapping example regions (a, b and c) located at the beginning of human chromosome 1 (red mark on ideogram, 1-250 bp) are shown here. Vertical gray separators between sub-regions indicate regions that are 1 base pair apart. Overlapping regions can be merged, joined, subtracted resulting in new regions objects as shown here. Associated source code snippets are documented in the Results section. Regions object flank (b, 5 bp) exemplifies bedr utility flank.regions creating flanking (up and/or downstream) regions of a specified length; +/-5 bp in the example shown here
