R help - Apr 2009 - Two different scales for the same axis in the same plot.

Hello,

Could anyone tell me how to plot data on two different scales in the same axis
in the same plot?
Here is my quandary:
The range of my X axis runs from 0 to 10, but the majority of my meaningful data
lies between 7 and 10.  The data from 0 to 7 is essentially noise.
Is there a way for me to present my data such that the range from 0 to 7 takes
up a smaller amount of space on the graph compared to the range from 7 to 10
so that I can see more of the details in 7 to 10?

Thanks in advance,

George Chen

Look at the gap.plot function in the plotrix package.  It may work for you, or
if not, looking at the code may give you some ideas of how to make a similar
plot with the different scales that you want.

Dear George,

Take a look at the twoord.plot function in the plotrix package.

HTH,
