plasmidplot: Publication-Quality Circular and Linear Plasmid Maps

Draws circular and linear plasmid maps with 'grid' graphics. Features are shown as colored arcs with optional arrowheads, callout labels that are laid out to avoid overlap, an automatic base-pair scale, and the plasmid name and size. A style is built from a handful of shape parameters, with presets as named combinations of them, and the layout follows the molecule's topology. Maps can be built up feature by feature or imported from 'GenBank', 'EMBL', 'FASTA' and 'SnapGene' files, whose format is detected from content rather than file extension. Restriction sites can be located in the sequence and labeled. Ships eight visual styles, including one inspired by the 'AngularPlasmid' JavaScript library, and seven categorical palettes checked for colorblind safety. Palettes from other packages can be used directly, as a color vector or as a palette function, and checked against the same criteria.
