Hi, I need to plot a graph with a circle of radius 1 and with a series of points of different size. The size of these points compared to the fixed circle is important and bears a meaning.
Here is the a simplified version of the code I'm using: x<-seq(0,2,by=0.2) y<-x z<-seq(0,1,by=0.1) angle<-pi/180*c(0:359) par(pty="s") plot(-2:2,-2:2,type="n") lines(cos(angle),sin(angle)) points(x,y,cex=z) I obtain points of the same size when cex=0.1/0.2/0.3/0.4 or cex=0.5/0.6/0.7 or cex=0.8/0.9/1.0. Please, does anyone know if there is a way of improving the resolution of cex in order to have 10 points *all* of different size (respecting the above written different values of cex)? The circle is fixed of radius 1 and the values of cex are in relation with that and they shouldn't be modified.
