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. -----Original Message----- From: Sander Oom [mailto:slist at oomvanlieshout.net] Sent: Tuesday, May 24, 2005 5:04 PM To: Hikel, Jerry Cc: r-help at stat.math.ethz.ch Subject: Re: [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.

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.
