[R] Forcing plots to "adjust-to-data"

[Jason Bond]

Hello.  In messing around with some of the graphical parameters using the 
par() function (setting margins for example), I've noticed that the plot 
doesn't always immediately respond to changes...for example when lines are 
added, if they are out of the range you need to physically find out what 
the new max range has to be.  Is there a companion function in R to the 
xlispstat function :adjust-to-data which dynamically forces the plot to do 
just that?  Thanks much again,

   Jason
