R help - Dec 2004 - Difficulty implementing "scales" in a lattice plot

Hello all,

I am rather new to lattice and have a simple question regarding formatting text
labels on the axes. I have looked through my own archive on lattice notes,
searched and examined 30 or so hits on Dr. Baron's search site, looked
through my MASS book, my Data Analysis and Graphics Using R book, R news
articles, and I have in my hand the lattice package instructions and have read
and re-read the "scales" section. Here is the problem I am having.

Scanf is a factor with 20 levels and the mean values for these levels are being
plotted with CIs.

I am trying to reduce the text size for the labels for this variable. The first
function below does not attempt to set the text size for the y axes, and all
works well.

  xx2 <- with(xx,summarize(q27a, llist(Scanf,bumo), smean.cl.boot,
conf.int=.90))
  Dotplot(Scanf ~ Cbind(q27a,Lower, Upper)| bumo, xlim=c(5,10),cex=.6,
par.strip.text=list(cex=.8), xlab="",main="", data=xx2)

Now, when I add to the above function, scales=(cex=.5), as I show in the
function below, the graph reduces the size of the y labels, but now, rather than
the text labels printing, the numbers 5, 10, 15, 20 appear on y--in other words
the numeric values are used.
  xx2 <- with(xx,summarize(q27a, llist(Scanf,bumo), smean.cl.boot,
conf.int=.90))
  Dotplot(Scanf ~ Cbind(q27a,Lower, Upper)| bumo, xlim=c(5,10), cex=.6, scales =
(cex=.5)), par.strip.text=list(cex=.8), xlab="",main="",
data=xx2)
So, seeking advice on how to reduce text size while retaining the text labels
for the Scanf variable.

This doesn't really make sense, since scales has to be either a list or 
a character string. Your example is not reproducible either, so I'm 
guessing, but perhaps you want 

  scales = list(y = list(cex = 0.5))

?
