Is it not obvious when you try it? Diameter. > What if the symbol is not a circle, what is the generic meaning of > size in that case? cex does linear scaling in each dimension. There is no generic definition of what cex=1 means: it depends on the device, the font (for pch >=32 except ".") or the symbols (pch=1...25). -- Brian D.
