[R] How to sort a grouped barchart?

[Greg Snow]

See my recent reply under the subject "bar order using lattice barchart()"

Running this code before doing your plot:

barley$variety <- reorder(barley$variety, barley$yield, function(x) x[2] )

will cause the bars in all the plots to be reordered such that 1931 Waseca is increasing, is that what you wanted?
