xyplot(y ~ x, ... pch = ".", cex = 2)
You may be able to get away with cex = 1 on certain drivers but for most
instances cex = 2 will be the smallest size.

Subject: [R] lattice : superpose symbols with a great many points
I like to use with xyplot (package lattice) the groups argument and
superpose.symbol to compare several curves. But, when there are a great
many points, the symbols are very close and the graph becomes
unreadable. Would there be an argument or a tip not to draw all the
symbols, for example the symbols could be drawn only every x points, x
given as an argument ?
