Re: [R] using contour() with x,y,z data?

I have read the contour help. I guess what I am asking is how to transform my data into a form that contour (or maybe some other functions?) so I can contour my x,y,z data. I know I can do it in SyStat. I'm hoping that R would allow me to do something like this.
