Plot an ellipse based on a correlation matrix
A utility function for quickly adding an ellipse to an existing graph based on a correlation matrix defining the ellipse's parameters.
plotSigmaEllipse(m,sigma,steps=5,col="black",lwd=1,lty=2)
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 |
lty |
The line type to use in the plot see |
lwd |
The line width to use in the plot see |
