The axes in rgl are a little messy.  It's been on my todo list for a 
long time to fix them, but there are a lot of details to handle, and 
only so much time.

Essentially there are two separate systems for axes:  the "bbox3d" 
system, and the "axis3d" system.  The former is the ones that appear and 
disappear, the latter is really just lines and text added to the plot.

You want to use the bbox3d() call.  For example,

bbox3d(xat=c(5, 10), xlab=c("V", "X"), yat=c(2,4,6), zunit=10)

for three different types of labels on the three axes.  It would be nice 
if axis3d had the same options as bbox3d, but so far it doesn't.
