Hi John,
a solution to your problem would be using strip.custom like this:
...
with(dat,xYplot(Cbind(ycomb, y.up, y.low)~x1|factor(grp),
data=dat,type="l", method="bands",
scales=list(y=list(relation="free"),x=list(alternating=c(1,1,1))),
ylim=list(c(0,1200),c(0,10000)),
strip=strip.custom(factor.levels=c(expression("Anls km"^2),expression("Plants
km"^2)))))
Best wishes,
Christoph
