Fault geology xyz to raster

Hi,

I have a 3-d geology problem. I have an xyz fault data set. I am able to
view the data set in R using plot3-d

That cannot be a function name, since it is invalid syntax.

but cannot create a raster from it. I
need to create a raster and export so that it can be read in arcscene. Can
anybody help?

"Create a raster"? You could try to be more vague, but it would be difficult. If you mean a png-formatted screenshot of something you are seeing on an rinteractive device, then:

   ?rgl.snapshot
