addEllipse: Add an confidence ellipses or other features to a ggpairs...

In amcdavid/SingleCellAnalysis: Tools for Analysis of Zero-Inflated, Continuous Data

Description

This function is necessary because there is no way to set aesthetics in ggpairs for only a portion of the plot matrix. If ellipseArgList is empty, then no ellipses will be drawn. If globalGGobjs is non-empty, then it will be added (+) to each panel. You might use this to alter the color scale

Usage

addEllipse(ggpairsObj, panels, ellipseArgList = list(lwd = 1, alpha = 1),
  pointsArgList = list(), globalGGobjs = list())

Arguments

ggpairsObj	output from ggpairs
panels	numeric vector giving rows/columns to modify from the _lower_ triangle of the plot matrix
ellipseArgList	list of ggplot aesthetics to be set to fixed values for the ellipses, eg, lwd or alpha
pointsArgList	list of ggplot aesthetics to be rewritten for the purposes of calling geom point, eg, size or alpha
globalGGobjs	vector of ggplot2 theme or scale elements

Value

ggpairs object with modified panels
