3D or 4D plot

Ideally I would want it to look like a rubik cube with each little cube color coded based on the fourth column (data column). Your suggestion might 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.

I have data on a regular grid in the format: x y z data. I would like to be able to plot them in 3d kind of like a volume or a mesh with colors. Is 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). Duncan Murdoch
