Draw Outline for A Data Track

Draw outline with subtracks for one data track. RCircos core components and graphic device must be initialized first. This function is mainly for internal use.

Usage

RCircos.Track.Outline(inside.pos=NULL, outside.pos=NULL,
    num.layers=1, chrom.list=NULL, track.colors=NULL)

Arguments

inside.pos

Non-negative numeric, inside position (relative to the centre of plot area) of the track.

outside.pos

Non-negative numeric, outside position (relative to the centre of plot area) of the track.

num.layers

Non-negative integer, number of sub-tracks lines. 0 for no sub-track line.

chrom.list

List of chromosome names for which outline will be drawn.

track.colors

Vector of color names for outline of each chromosome.
