Those two planes should look like "bottom" of that 3D plot [i.e. like Grid-lines].I already gone through "$plane3d" but could not get through. In the help page, a description is given with a regression line, however I could not understand how I can implement that in my problem.
s3d <- scatterplot3d(dat, lab.z=2, scale.y=0.7, angle=20)
s3d$plane3d(2,0,0, "solid", col="grey")
