R help - Sep 2006 - plot a new picture against an old one to see the difference between them

Hello, useR:,

Suppose I have two plots made by using contour() function, say Cont1 and Cont2
respectively.

They have slightly difference because of the two slightly different data  I
used.

I want to see the difference between them so I want to plot Cont2 on Cont1, are
there any methods to plot it without filling the frame of Cont1 totally of
Cont2.
I mean, how I can integreate the two plots together that they kind of have
weighted colors?

Thanks very much in Advance!

Dear Roger,

Thanks, that's really helpful,  do you know how to deal with it if the two 
plots are  generated by plot(), not by contour().

Best,

Leon

Hi R users:

How can I have several subscript number with a comma in a plot.

I would like to have the LaTeX equivalent of

x_{i,j}.

I try:

plot(1:10,1:10,type="n")
text(5,5,expression(x[i,j]))

but it doesn?t work.

Thank you for your help.

Try:

text(5,5,expression(x[i * "," * j]))
