hi ,R user folks . Nowadays I read a paper which draw a probability ellipse circle figure shown in the appendix. I wonder how to draw this figure by R ? the x-axis and y-axis both express the error but in different direction . -- TANG Jie Email: totangjie at gmail.com Tel: 0086-2154896104 Shanghai Typhoon Institute,China

Also try RSiteSearch("ellipse")
