R help - Dec 2002 - Mutiple page trellis plots with relation = "free" or "sliced"

Hello,

Has anyone out there encountered a problem like this:

xyplot(Plasma ~ Serum | Analyte,
       data = sp.df,
       aspect = 1,
       layout = c(1, 1, 200),
       scales = list(relation = "free")
       )

Gives the error: 

Error in pretty(x[is.finite(x)], ...) : x must be numeric

On the other hand, this works (but I don't want the default of having
everything on the same page):

xyplot(Plasma ~ Serum | Analyte,
       data = sp.df,
       aspect = 1,
       # layout = c(1, 1, 200),
       scales = list(relation = "free")
       )

and this works (but I don't want the default of using the same axes
limits for all plots):

xyplot(Plasma ~ Serum | Analyte,
       data = sp.df,
       aspect = 1,
       layout = c(1, 1, 200)
       # scales = list(relation = "free")
       )

For my present situation, I can work around this by creating multiple
plots in a loop, but I am wondering if I am missing something about the
way multi-page plots work. 

Thanks for any help.

No, this is supposed to work. I'm not sure where the problem might be, but
it
could have something to do with panels without any data in them. Does that 
happen in your case ?

Yes. The number of pages in my layout argument (200) was greater than
the number of unique values in my conditioning variable (168). Changing
to layout = c(1, 1, 168) solves the problem. 

Very sorry, I should have thought of that. 

Thanks so much for your response, and many, many thanks for implementing
lattice. It is incredibly powerful and a joy to use.
