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.
