Highlight a plot area with transparent color cross one or more tracks. RCircos core components and graphic device must be initialized first.
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)
Vector with chromosome name, start and end position to be highlighted.
Vector of non-negative integer, which track or track(s) to be highlighted.
Character vector, location relative to the ideogram, either "in" or "out".
An RGB color definition, alpha value must be defined.
Non-negative numeric, inside position (relative to the centre of plot area) of the track.
Non-negative numeric, outside position (relative to the centre of plot area) of the track.
