Yes, they are next to each other, but in different panels, as expected
when using a formula like that. I should have been more explicit saying
that I want the conditioning variable to show within a panel.

I disagree. IMHO, I don't think the sole purpose of lattice is to put
plots in different panels. There are several cases, where (I think)
lattice can "mark" groups of data in a single panel more efficiently than
other tools. One may or may not need other conditioning variables to show
in different panels.
