How can I improve the aspect of the lines in a line plot? I want to avoid that between two points the line joining them is breaked into "steps". For example: plot(1:100,sin(1:100)) lines(1:100,sin(1:100),type='l',lwd=2) I get that the line joining two points is made up of vertical segments, what I basically want is that there are more segments between two points so I get the aspect of a true line. Thanks, Angel
