Calculate Zoomed Index of Circos Plot Positions for Genomic Intervals

Scale up the index of Circos plot positions of a small range for zoom-in plot with data that require two positions to plot e.g., tiles and parallele lines. This function is mainly for internal use.

Usage

RCircos.Zoom.Paired.Plot.Positions(zoom.data=NULL, zoom.pos=NULL)

Arguments

zoom.data

Data frame, data to be plotted onto zoom area.

zoom.pos

Non-negative integer, index of RCircos base plot positions.

Value

A two columns integer matrix representing the index of RCircos plot positions.
