R help - May 1998 - R-beta: adjusting y-axis scale with multiple lines in plot

Hello --

I am plotting multiple densities in a single plot. If the max of a new
density (added with 'lines()') is sufficiently larger than that of the
one first plotted (using 'plot()'), the new density is cut or
trucated off of the figure. Is there a simple way of adjusting the
yscale after all lines have been added? 

Or is the procedure to be used to first estimate all densities, the plot
the first one with 'ylim=c(0,max())' and the add the lines one by one?
If anyone has pondered on and solved this, I'd be very grateful for the
solution. 

Regards,
Markus

Yup. That's the general procedure. Some kind of autoscaling would be
nice to have some time in the future, but currently the graphics
model in R (and S-plus) is that of a hardcopy device (e.g. a plotter)
with "no eraser".

There's also the option of using matplot(), although that'll lose the
facilities of plot.density.
