[R] Controlling Order of Panels in Lattice Trellis Plots

[Rich Shepard]

   With multiple panels in a lattice trellis plot the sequence is, for
example, 1, 10, 11, 12, 2, 3, 4. I want the sequence to be 1, 2, 3, 4, 10,
11, 12.

   Reading ?strip.default and the appropriate section in the Lattice book I'm
not seeing how to specify the 'human' numeric order rather than the computer
numeric order.

   A pointer will be appreciated.

TIA,

Rich
