[R] Question about Title of Plot

[Bernardo Rangel Tura]

Dear all,

I'm a brazilian medical doctor that I research use of likelihood in the  medical research.
I need to do a plot with this layout:

---------------------------------------
|            Major Title              | 
|                                     |
|   Title             Title           |
|  --------          --------         |
|  |       |         |       |        |
|  |       |         |       |        |
|  |       |         |       |        |
|  |       |         |       |        |
|  --------          --------         |
|                                     |
---------------------------------------

My original code was

par(mfcol = c(1, 2))
title(main="Likelihood Analysis")
plot(or,lor,type="l", ylab='Likelihood',main="Odds Ratio")
plot(tau,lor,type="l",xlab=expression(tau), ylab='Likelihood',main="log(Odds Ratio)")

It creates this layout
---------------------------------------
|                                     | 
|                                     |
|   Title             Title           |
|  --------          --------         |
|  |       |         |       |        |
|  |       |         |       |        |
|  |       |         |       |        |
|  |       |         |       |        |
|  --------          --------         |
|                                     |
---------------------------------------

How do I do for you create the wanted Layout?
Thanks advanced for all
