In bryanhanson/ChemoSpecUtils: Functions Supporting Packages ChemoSpec and ChemoSpec2D

Compute Confidence Ellipses

Description

Internal function. A utility function which when given a x,y data set computes both classical and robust confidence ellipses.

Usage

.computeEllipses(x, quan = 1/2, alpha = 0.025)

Arguments

x	As per corr.plot.
quan	As per corr.plot.
alpha	As per corr.plot.

Value

A list with the following elements (a simpler version of that in the original function corr.plot):

x.cls	The x values for the classical ellipse.
y.cls	The y values for the classical ellipse.
c	The correlation value for the classical ellipse.
x.rob	The x values for the robust ellipse.
y.rob	The y values for the robust ellipse.
r	The correlation value for the robust ellipse.
