different plot symbols in key using xyplot

Stephen Kennedy-9
I'm using xyplot in a very simple way---a scatter plot of several data  
sets.  I'm having a problem getting auto.key to display different  
point characters.

The following produces a plot that employes different colors, all with  
pch(1), for the different groups, with a matching key.

xyplot(Force~Time, rawData, groups=Sample, panel = panel.superpose,  
auto.key=TRUE)


The following produces a plot that employs different symbols (and  
colors) for the groups, but the key still uses pch(1) for all groups.  
I assume I need to set some more general option, but haven't found it  
yet.

xyplot(Force~Time, rawData, groups=Sample, pch=0:18, panel =  
panel.superpose, auto.key=list(space="right", pch=0:18))


What I would really like is a plot with different symbols, all with  
black color.  The following works for the plot, but again has no  
effect on the key.

xyplot(Force~Time, rawData, groups=Sample, pch=0:18, col="black",  
panel = panel.superpose, auto.key=list(space="right", pch=0:18))


Thanks,

Try this:

xyplot(Sepal.Width ~ Petal.Width, data = iris, groups = Species,
   par.settings = list(superpose.symbol = list(col = 1, pch = 0:2)),
   auto.key = TRUE)
