[R] different x-axes in Lattice

[Peter Ehlers]

If I understand you correctly, then what you propose makes
very little sense to me. In your barley2 example, I certainly
would want to see the empty space for 'Velvet'. If you want a
separate plot for each site, with no common 'variety' axis,
then just build separate plots. Of course you would lose the
ability to easily scan the vertical direction to compare
varieties at different sites.
