[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.

RE: [R] Plot range resizing when adding additiona lines
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,
Matt Wiener

You can check the range of all items to plot and take the minimum and
maximum value across all items. Then draw the plot with the axis range
explicitely set to 'minimum'-'maximum'!
That is assuming you know the items you are drawing before hand.

RE: [R] Plot range resizing when adding additiona lines
That's what i wound up doing -- i am totally new to R, so i wasn't sure
if there were an easy way of getting the min and max values of a data
frame, but i tried that and it worked out well. Thanks.
