Re: [R] contour lines on persp plot

One quick idea is to use the functions - contourLines() to calculate the contour lines - trans3d() to transform the 3D coordinates into the 2D space you will be plotting into - polygon() to plot the contour lines Uwe Ligges Jack Siegrist wrote: Hello folks, I am a beginner R user. I have

[R] contour lines on persp plot
