R help - May 2006 - Increase the number of plotting characters in dotplot (lattice)?

Dear list,

I am using the dotplot function of lattice and like it very much.
However, in some of the plots, I have more than 7 categories that I
would like to represent by different plotting characters in the graph,
which is  a problem. For the categories after the 7th, the plotting
characters are recycled, creating a confisuing graph indeed.

So, my question is: how do I increase the number of unique plotting characters?

/Fredrik

library(lattice)

show.settings()

trellis.par.set(superpose.symbol = list(pch = 1:16), dot.symbol = 
list(pch = 1:16))

show.settings()

?trellis.par.get
