Want to draw 3D cylinder objects
Hello,
I want to draw 3D cylinder objects in R.
Given is the length and the diameter of the cylinder.
Has anybody an example?
Thank you very much!
Best regards

rgl: cylinder3d() with elliptical cross-section
For a paper dealing with generalized ellipsoids, I want to illustrate in
3D an ellipsoid that is unbounded
in one dimension, having the shape of an infinite cylinder along, say,
z, but whose cross-section in (x,y)
is an ellipse, say, given by the 2x2 matrix cov(x,y).
I've looked at rgl:::cylinder3d, but don't see any way to make it
accomplish this. Does anyone have
any ideas?
thx,

Rcmdr and scatter3d
Hi folks,
I'd like to use scatter3d (which is in R commander) to plot more than one
dataset in the same graph, each dataset with a different color. The kind
of stuff you would do with "holdon" in Matlab.
I read a recent message that was posted to this list with a similar
problem, but I couldn't understand the reply. Could someone give me one
example? How do you plot subgroups
