All, I am wondering how one might add a reference line or plane to a cloud or wireframe plot. I have been unable to figure this out. Let's say I would like to draw a reference for some value of wt in the example below: cl <- 54.1 age <- 10:80 wt <- 25:160 sim <- expand.grid(age = age,wt = wt) sim$cl <- cl*(sim$wt/70)**0.412 * (sim$age/50)**0.152

Dear All,   using the example from the package scatterplot3d I created a 3d plot as follows:   x <-rnorm(500,50,2) y <-rnorm(500,5,1) z <-rnorm(500,6,1) scatterplot3d(x, y, z, highlight.3d=TRUE, col.axis="blue",col.grid="lightblue", main="scatterplot3d - 1", pch=20)   I would like to ask if anyone could help me with the following:   1. I would like to draw  a

> It should be a 2D slice/plane embedded into a 3D space. I was able to come up with the plot, attached. My intention was to plot national boundaries on the surface of a sphere. And put the slice inside. However, I haven't (as yet) worked out how to get the coordinates for the boundaries. Let me know, if of any value. And I'll post the code. (But needs to be polished first)

Thanks for your idea. It should be a 2D slice/plane embedded into a 3D space. Could be static, I just need to make a single figure from it for illustration of the Earth together with its interior in 3D. So, the interior would be a slice in 2D along a fixed longitude. And along this 2D slice would be a heatmap. Again, embedded in 3D, since it would be shown as a slice of Earth in 3D. Duncan?s
