R help - Sep 2009 - R package for visualizing/analyzing accelerometry data?

Hello All -

Any recommendations or suggestions for neat ways to visualize data
taken from a 3-axis accelerometer? My study species is aquatic, so I
would be interested in movement in the 3 dimensions in addition to
being able to incorporate the time series as well. Is there a package
in R that might be useful for this?

Thank you in advance,
Jen

rgl should let you draw segments (maybe even arrows) in pseudo 3D  
between sequential locations. I wonder if you could trick persp into  
doing it as well?

scatterplot3d would be another avenue to explore.

As David mentioned, rgl can draw 3D figures, but the problem of 
visualizing a 3D path in an informative way is not easy.  The new 
cylinder3d function in rgl might give paths that are easier to decode 
visually than line segments would be; it also offers the possibility of 
encoding orientation in the shape of the cylinder.  I'd be interested in 
hearing how this goes.
