RCircos.Clear.Track {RCircos} | R Documentation

## Erase One or More Data Tracks

### Description

Erase one or more data track or all tracks from current track to the center of plot area. RCircos core components and graphic device must be already initialized.

### Usage

    RCircos.Clear.Track(track.num=NULL, side=NULL, to.center=FALSE,
        inside.pos=NULL, outside.pos=NULL)

### Arguments

`track.num` | Non-negative integer, representing the ordinal number of the plot track to be erased.
`side` | Character vector, either "in" or "out", representing the position related to chromosome ideogram. It could be NULL is both inside.pos and outside.pos are defined.
`to.center` | Logic, FALSE for erasing current track only and TRUE for erasing all tracks from current track to the center of plot plot area.
`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.
