[R] how to make point character thicker in xyplot?

[array chip]

Thank you Greg. I also got it work by using panel.points (lwd=2) instead of 
using panel.xyplot()

There is probably a simpler way, but if you want full customization, look at 
panel.my.symbols in the TeachingDemos package.

Is there anyway to make plotting point character being thicker in xyplot? I mean
not larger which can achieved by "cex=2", but thicker. I tried lwd=2, but it
didn't work. I know "lwd" works in regular plot() not only for lines, but also
for points. For example

plot(1:10, lwd=2)

Thanks

John
