Abby,
The rgl library has a function called 'select3D' that you might try.
This allows you to select particular points from 3D data: similar to
the 'locator' function in 2D.
We are currently trying to develop routines for 3D data capture in R,
including digitizing points, curves, and surfaces. However, we are
at a very early stage in the process, and at this point what we have
is nowhere near ready for distribution.
I hope at least that the 'select3D' function gets you started on your
project.
Best,
Dean

Any R experts out there?
I want to capture landmarks and eventually semilandmarks off my 3D
point cloud data obtained from laser scans. I picked up the
Morphometrics with R book and have found both the book and R very easy
to use.
However the 'locator' function used for capturing the landmarks in 2D
does not seem to work in any of the 3D plotting packages. I tried
scatterplot3d, cloud and now rgl. rgl is great because it lets you
rotate and zoom with the mouse. Is there a function I'm missing that
will also let me select landmarks like 'locator' does for 2D?
Thanks for your help!
Abby
