Hi all, I have a simple question and couldn't find any post on this. When plotting simple scatterplots (other plots as well), e.g., x<-rnorm(30, 10, 1) y<-rnorm(30, 10, 1) plot(x, y, pch = 15, cex = 1), the points, even those close to each other, may have visibly different sizes. Do you know what's going on with that? Thanks in advance, Marcin
