rgl package don't draw points with a color over points with another color
I want to plot points with different colors to show different
selections of points in a 3d plot.
My problem is that if I plot a red point at a location where already a
blue point was plotted, than the point is still blue.
Is there a parameter or so which can be used to draw over a existing point?
Example:
> require(rgl)
> open3d()
> plot3d(a<-c(1,2,3,4,5),a,a,type="l",
