### Description

Highlight a plot area with transparent color cross one or more tracks. RCircos core components and graphic device must be initialized first.

### Usage

    RCircos.Area.Highlight(highlight.area=NULL, track.num=NULL,
        side=c("in", "out"), hightlight.color=rgb(0.5, 0.5, 0, 0.5),
        inside.pos=NULL, outside.pos=NULL)

### Arguments

`highlight.area` | Vector with chromosome name, start and end position to be highlighted.
`track.num` | Vector of non-negative integer, which track or track(s) to be highlighted.
`side` | Character vector, location relative to the ideogram, either "in" or "out".
`hightlight.color` | An RGB color definition, alpha value must be defined.
`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.
