I have the same question/problem.
I have a UTM plot, so the axes are in meters, and I need to represent each
point of 50*50 m. It is any way to do it?

Asunto: [R] Plot symbols dimensions

I am writing some code to obtain publication-like plots (like the ones can
be obtained with SigmaPlot). I am not able to find the dimensions of a
point. Parameters like cex make you able to make it bigger or smaller but I
need to know the exact dimension (in relative coordinates :
if my plot is 640x480 a dot plotted with cex=1.5 will be...)
