how to make lines() meet axis in autoscaled coordinate system?
...does what I want, BUT the second leg does not touch the x-axis since the auto-scaling of the y-axis does not start at'0' but slightly negative. I could now adjust the line length by 'trial and error' to suit my needs, but I'd prefer a generalizable solution like >lines(c(<some_macro_for_y-axis_position>,time1,time1), + c(1,1,<some_macro_for_x-axis_position>),lty=3) Can somebody help me out with this? Thanks, Joh
