R: Draw Outline for A Data Track

RCircos.Track.Outline {RCircos} | R Documentation

## Draw Outline for A Data Track

### Description

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.
