You're right, Titus. I misunderstood. It looks like index.cond
has to be in 1:(number of panels being plotted for factor f).
While this can arguably be covered by the phrase "valid indexing
vector", I agree that this could be made more explicit.

Peter, thanks for your response! The problem is not how indexing
works, but rather the question what is being indexed here. If I
understand the description correctly then it is wrong. In the special

data frame it coincidentally h

The answer is apparently:
xyplot(dur~roi|trial, d
I'd like do a simple xyplot with customized order of panels and try to
understand how to use index.cond for that. Several attempts didn't
deliver the correct results. Now, I noticed the following:
