getDataPanelBoundingBox: getDataPanelBoundingBox

In karyoploteR: Plot customizable linear genomes displaying arbitrary data

Description

Return the bounding box of a data panel in plot coordinates

Usage

getDataPanelBoundingBox(karyoplot, data.panel)

Arguments

karyoplot	a karyoplot object returned by a call to plotKaryotype
data.panel	a valid data panel name (i.e. 1, 2, "ideogram", "all")

Details

Given a KaryoPlot object and a data.panel name, return the region where the data panel is placed. The returned values are in plot coordinates, that is, the coord.change.function has been applied.

Value

Returns a list with four elements (x0, x1, y0 and y1), each of them an integer with the plot coordinates for the data.panel

Note

A user is not expected to need this function. It is mainly used by plotting functions, specially when clipping the plot in a zoomed region.
