Re : three-dimensional (volumetric) estimation from x,y,z
You may use the "geometry" package and the "convhulln" function.
This will allow you to compute the convex hull volume of a set of
points in a n-dimensional space.

partial mantel
...n other words, in a community ecology analysis, I would like to calculate
the correlation between two dissimilarity matrices, controlling for a third
distance matrix representing geographical distances between sites.
Thanks!

Extract values of a two-factor table and duplicate them into a three-factor table
...something cleaner ? Do you have an idea ?
Thanks !
Mel
PS: those tables are supposed to be very large datasets of several thousands of rows.

interactive rotatable 3d scatterplot
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 available for a package that will work?
