Hi Try
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.

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 ?
