You need to leave some room in the outer margin and use mtext to put the
major title on the page:
par(mfrow = c(1, 2), oma = 0.1+c(0,0,4,0))
plot( ...first plot... )
title( ... first title ...)
plot( ...second plot... )
title( ...second title... )
mtext("Major title", line = 2, outer = TRUE) ## this is the trick

Subject: [R] Question about Title of Plot
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
