It really sounds like you want to use points(). Maybe I'm missing the true question but ellipsePoints returns a 2 column matrix of point coordinates so passing it's output to points() should plot those points on whatever plot you currently have open (in this case the plot of the previous ellipse). If you're looking for an alternative way to do it, you could rbind the outputs together and then plot the whole thing: allPoints<-rbind(ellipsePoints(2,5, alpha = 30),ellipsePoints(2,5, alpha = 60)) plot(allPoints)
