rgl plot3d plotting points (spheres) with vertical lines to x–y plane

Question

I am using rgl plot3d function to plot 3d points from Multidimensional scaling. So far I can draw the points as spheres using type="s" , I can rotate the plots as I need:

plot3d(x,y,z,type = "s", col=rainbow(20), size= 4,xlab="F1",ylab="F2",zlab="F3",main=title.main,box=TRUE,top=TRUE).

I know that I can get this using rgl scatter3d function but this is used scatters/regression ... and I can also do this with scatterplot3d , but I can't rotate this one. I would have imagined that if it is possible to do this using rgl scatter3d function. I would expect that it would be easy in rgl plot3d function... but I haven't figure out how to plot these vertical lines from the points(spheres) using plot3d ? If I use type = "h" it only draws vertical lines to the x–y plane and I don't see a separate parameter to draw the spheres.

Answer 1

Try:

> x=1:10
> y=21:30
> z=51:60

> plot3d(x,y,z, type='s')
> plot3d(x,y,z, type='h',add=TRUE)
