user error described in the FAQ (was [BUG?] xyplot in loop does not work)

Do you mean, Dr.Ripley, one has to carefully read this
100-pages-FAQ-manual  one time per year or even more often?

I assume he means you should read it *before asking questions*, or at 
least before suggesting that something is a [BUG?]. It does 
have an index, one entry of which is
   7.22 Why do lattice/trellis graphics not work?

Reading the FAQ index is no more work than you are asking other people to 
do, and it will get you an answer even faster.  Of course, you *did* get 
an answer to your question, very quickly, so reading the FAQ may seem 
inefficient.

I guess this FAQ-entry about fully intuitive behaviour of xyplot came
last year, right?

Well, the behaviour predates the R implementation and is described in 
help(xyplot).  Obviously no-one except you thinks it it fully intuititve, 
or it wouldn't be in the FAQ.
