[R] bwplot scales in alphabetical order

[Peter Ehlers]

Tim,

Add the argument as.table=TRUE to your call:

   bwplot(y~x|id, horizontal=FALSE, as.table=TRUE)

I have already read that this is due to the way factors are treated, and I have to redefine the levels of the factors.  However, I have failed.
