Erase One or More Data Tracks — RCircos.Clear.Track • RCircos

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.
