Drawing ellipse in R

Question

I want to make ellipse in R. The code is given below:

library(car)
A      <- matrix(c(2.2, 0.4, 0.4, 2.8), nrow=2)
ellipse(c(0, 0), shape=A, radius=0.98, col=&         


        

Answer 1

supply the argument add=FALSE and it will create a new plot instead of trying to add to an existing one. There is also an ellipse package that I've used if you want another option.
