You should get no lines at all, as you have not specified that lines be
drawn. Use the "type" argument to do so.

xyplot(rnorm(5) ~1:5,pch=4)  ## points only
xyplot(rnorm(5) ~1:5,pch=4,type="b",lwd=4) ## points with thick lines

read ?panel.xyplot carefully (the default panel function for xyplot) for
details

Cheers,
Bert
