The grid.points function can accept a lwd argument:
xyplot(4:5~4:5, groups=4:5, panel=function(x,y,groups,...){
panel.xyplot(x,y,...,col='white')
grid.points(x,y, gp=gpar(cex=10, lwd=7) ) },
auto.key=TRUE)
This probably means there is a less hackish way of setting the lwd.points, but
I don't find it in my sequesntial following through the lattice help pages.
