Hello,


I'm  doing xyplot(s) with groups  using the following code and "lattice" 
package

xyplot(V8  ~ V7 | cut(V17,c(0,10,20,100),include.lowest=T 
)+cut(V18,c(0,10,20,100),include.lowest=T ), 
pch=20,groups=as.array(c("HPM","HPS","HCJ","HCN")[V19]),data=A1,auto.key=list(space="bottom",pch=20,points=T))

The plots are corresponding to what I want except the legend with 
auto.key where the pch=20 option is taken into account

What I should do to have pch=20 in the plot and in the legend

Thanks
