Hi Duncan,Thanks! But I still get a little confused about outer() func. Would give me a simple example to contour it? Just like the formula x^2 + y^2 + x + y -5 = 0. (Sorry I am a newbie to R, found really hard to use the R manual) Thanks, Hao On Sat, Jul 4, 2009 at 7:10 AM, Duncan Murdoch wrot

Hi, I want to plot a polynomial in the form like ax^2 + bxy + cy^2 + dx + ey + f =0 without solving it(since I may have 3 or 4 dimensional polynomial and it's really hard to solve). Is there any way to plot this kind of polynomial? Thanks a lot! Hao -- View this message in context: http://www
