Well, you have already specified 'layout', so the only issues are what
order to plot the panels in, and where to plot them. I'm not sure which
of these issues you are interested in (perhaps both).
To skip some panels, try 'skip', e.g., skip = c(F,F,F,T,F,T,F,F,F)
To change the order, you need to use index.cond (see below).

perm.cond: numeric vector, a permutation of '1:n', where 'n' is the
number of conditioning variables. ...
In your case, n = 1, so this doesn't make sense.

index.cond needs to be a list of length n (one component for each
conditioning variable), so you probably want
update(plot,index.cond=list(c(3,2,1,4,5,6)))
