Ideally I would want it to look like a rubik cube with each little cube

work if I could color code based on data in the fourth column.
Thanks
There's no primitive "cube" symbol in rgl, but you can get an array of
colour-coded spheres:
x <- rep(1:3, each=9)
y <- rep(rep(1:3, each=3), 3)
z <- rep(1:3, 9)
colours <- terrain.colors(27)
plot3d(x,y,z,col=colours, type="s", size=10)
If you really want cubes, you can put them together (start with cube3d()
to get one, and build on that), but it's a lot of work.

that possible in R and how?
There are lots of ways, depending on what you want the plot to look like.
One is
library(rgl)
plot3d(x, y, z, col=color)
(assuming you also have a variable indicating the color to plot).
