[R] Customizing axis labels with alternating in lattice

[Waichler, Scott R]

I would like to have complete control over which plots and which
axes have labels in a lattice figure.  I tried lots of vectors for the
alternating setting in scales, but none worked.  Here is what I
would like to do for a 2 col x 3 row figure, where the x designates
a location I would like to have axis labels:

      ___________
    x |_____|____|
      |_____|____|x
    x |_____|____|
         x     x
