Hello What is the purpose of Roman numbering of pages in Samba HOWTO Collection? Cl<

I estimate some parameters and I want to print them (pretty) on my plot: # somehow estimated parameters z<-c(1.543523e+00, 1.23453e+00, 3.454000e+00) x<-seq(-1,1,length=100) plot(x,z[3]*x^2+z[2]*x+z[3],type="l", main="My nice plot of the estimated function") zs<-format(z,digits=4,scientific=FALSE,trim=TRUE) text(-0.9,7,expression(1.54*x^2)) # is

I'm happy to announce that I've added Roman Kagan as a committer to the https://github.com/libguestfs/libguestfs repo. Roman has contributed many high quality patches over a period of one year.

I want to plot something (eg a circle) with a fixed ratio of the x and y axis, or (even better) with a fixed size when I print it. Output should then be a circle (actually it'll be someting more complicated) with radius 5cm and not an ellipse. I'm _sure_ this is not new, but after looking 45min for a solution, I post here... Thanks for help Thomas
