Dear R users,
I have a question regarding the use of xyplot in the lattice() package.
I have two factors (each with two levels), and I´d like to change the
order of the panels in a 2x2 panel layout from the default alphabetic
order that R uses based on the names of the factor levels.
My approach is (in principle)
xyplot(y~x|Factor1+Factor2)
Let´s assume, my factor levels for Factor1 are A and B,
and for Factor2 they´re C and D, respectively.
Now the default arrangement of my panels would be (from bottom top left
to bottom right): "BC","CA","BD","AD"
What I´d like to have is "BD","AC","BC","AD".
Can anyone tell me how to solve this problem easily?
I´ve read that using "perm.cond" and/or "index.cond" could solve this
problem, but couldn´t find an appropriate example, unfortunately...
Thank you very much for your help!
Regards,
Christoph
