I'm running Ubuntu linux 7.10 with a 32bit processor, thus the problem
is not arising from 64bit issues.

The problem is arising because graphical effects are certainly turn-on
on the computer.
I deactivated the graphical effects and was able to rotate the 3D surface plot.
Turning effects on bring me back in the original state of a non rotating scene.
It seems that it is more an openGL issue.
I would like to create a 3d scatterplot that is interactive in the sense
that I can spin it on its axes to better visualize some PCA results I have.
What are the options in R? I've looked at RGL and perhaps it will suffice
but it wasn't apparent from the documentation I found.
Any demo scripts
Hi Mark,
Try using ggobi via Rggobi. ggobi is aimed at higher dimension
multivariate data but it does a very useful service in 3-D projections,
do a manually controlled tour ... I've used this to tweak PCA results
and find fine structure,
Richard
