Hello,
	I'm using lattice and opened an X11 device with the following call
	X11(width=5,height=5,pointsize=1)
	I then ran the following code
	
	library(lattice)
	x<-rnorm(30,sd=2)
	y<-runif(30)
	xyplot(y~x,pch=".",col="black",cex=1)

	If i remove "cex=1", not all the points are plotted. From ?X11, i  
read,"pch='.' with cex=1 corresponds to a rectangle of sides the  
larger of one pixel and 0.01 inch"

	By way of information, i'm using a Dell 30", where the the pixel  
pitch is 0.250mm(0.0098 inch).

	My question, why is that some of the points are not being plotted  
when remove cex=1 ?

	Regards
	Saptarshi
