In traditional, or "base" graphics, see "matplot", which does exactly what
you describe.

  You can also look at lattice graphics, which will give you flexibility to
plot in a single panel or multiple panels.

Hope this helps,

Subject: [R] Plot range resizing when adding additiona lines

Hi -- I have searched the documentation and archives on graphing
capabilities in R for the past couple of hours, but I haven't been able
to find anything directly related to my problem.

I want to create a plot with several lines displayed on it. I want each
line to be displayed in a different color, so it seems the only way to
do this is to create a plot and then use the lines() function. However,
once i create the original plot, when I add new lines to the plot, the
axes range stays the same, and the new lines often extend beyond the
range of the original axes, cutting off the data of the added lines.

Is there any way to force the plot to resize it's axes range when new
lines are added, or is there some other optional way of implementing
this? Thanks.
