plot3d crashes R

Hi Duncan,

I've just read the help for the plot3d function you've written 
and tried out the example code given at the
bottom of the page. I then modified the function by adding
 an aspect ratio of 0.1 and ran it again, which
crashed my R. I am using 2.12.2 on Windows, if that tells you anything.

Can you please:

(1) post the result of sessionInfo()
(2) post *exactly* the code that you ran -- e.g. was it

       open3d()
       x <- sort(rnorm(1000))
       y <- rnorm(1000)
       z <- rnorm(1000) + atan2(x,y)
       plot3d(x, y, z, col=rainbow(1000), aspect=0.1)

?

  This seems to make some kind of superficial sense, but it
doesn't really -- if you look inside aspect3d() [which is eventually
called by plot3d -> decorate3d] you'll see that it has no effect.
On the other hand, 

       plot3d(x, y, z, col=rainbow(1000), aspect=c(0.1,1,1))

gives a bounding box that is skinnier in the x-direction.

  Nevertheless, it shouldn't crash.

  My sessionInfo():

sessionInfo()
