Sorry about that, when I asked before I meant that I had tried your
proposed syntax. That has a problem, and it is that it uses the same set
of values for the character expansion *for both groups*, and it is not
what I wanted to do. If you plot the data (now a reduced set! sorry!)
you'll see that both plots are exactly the same: I have data on the same
positions, but the values that I want to represent with cex are
different for each group. The intention is to take advantage of the fact
that (I think that) lattice will use the same scaling on both plots.
I think I have found it...
# This is just to make sure that a group has a value of 1 and the other of 2
dd$z <- (1:50)%%2 + 1
xyplot(y~x|group, panel=function(x,y,subscripts){panel.xyplot(x,y,
cex=dd$z[subscripts])}, data=dd)
Cheers,
