Dear Prof Brian Ripley Thanks for replying to my question. I am sorry but it is still not clear to me if there is a way to handle an "intermediate" line width. In my windows system when I create a figure with 4 plots par(mfrow=c(2,2),lwd=1) the lines look a bit too thin and using lwd=2 makes them look a bit too thick, and if I use 1.5 it makes no difference. i.e
par(mfrow=c(2,2)) plot(sin,lwd=1)#Too thin plot(sin,lwd=1.5)#Same as lwd=1 plot(sin,lwd=1.99)#Same as lwd=1 plot(sin,lwd=2)#Too thick Regards Francisco >From: Prof Brian Ripley <[EMAIL PROTECTED]> >To: "Francisco J.
