RCircos.Zoom.Area.Outline {RCircos}

Draw Outline for Zoom Plot Area

Description

Draw outline and subtrack lines for zoomed-in area of a track in outside of chromosome ideogram. RCircos core components must be initialized first. This function is mainly for internal use.

Usage

RCircos.Zoom.Area.Outline(zoom.pos=NULL, inside.pos=NULL,  
    outside.pos=NULL, num.layers=5, fill.col="white")

Arguments

zoom.pos

Non-negative numeric vector, the index of RCircos plot position.

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 in a data track.

fill.col

Character vector for color name to fill the polygon.
