View source: R/plotSigmaEllipse.R

Description

A utility function for quickly adding an ellipse to an existing graph based on a correlation matrix defining the ellipse's parameters.

Usage

1
plotSigmaEllipse(m,sigma,steps=5,col="black",lwd=1,lty=2)

Arguments

m

A vector of length 2 containing the centres of the ellipse (i.e. the means of the ellipse).

sigma

A 2x2 matrix representing the correlation matrix that defines the ellipse.

steps

A visual rendering option that sets the number of step-size and hence resolution of the points used to draw the lines defining the ellipses. The larger the value, the more angular the ellipses will appear.

col

The colour to use in the plot see par.

lty

The line type to use in the plot see par.

lwd

The line width to use in the plot see par.
