R help - Feb 2013 - Border width on symbols plotted with the lattice package

Dear list members,

I can't figure out how get 'xyplot' or 'dotplot' in the
'lattice'
package to respect the 'lwd' value for specifying the border with for 
*symbols* (for lines it works fine). Example:

-----
# Base graphics works fine (gives a 'fat? circle)
plot(5, cex=10, pch=21, lwd=10)

# But 'xyplot' or 'dotplot' doesn't
library(lattice)
xyplot(4:5~4:5, groups=4:5, par.settings = simpleTheme(cex=10, pch=21, 
lwd=5),
         auto.key=TRUE)
-----

For 'xyplot' or 'dotplot' the border stays thin no matter what I
set
'lwd' to. However, the symbols shown in the *legend* has the
'lwd'
correctly applied.

How can I fix this? Or is it simply a bug in the 'lattice' package?

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.

Thanks, both David and ilai. The ?lex? solution seems to work very well.
