R help - Aug 2008 - I have an array of plots and I would like to put a title on the whole array.

Hi, all,

Does anyone know of a way to get a title on an array of plots?  I have  
tried to use title, mtext, and text to get the title on the array, but  
to no avail.  I would like something like the following.


title("Big Array")
par(mfrow=c(2,4))
plot(x1,y1)
plot(x2,y2)
..
..
..

Much appreciated,
Art

par(mfrow=c(2,4), oma=c(0,0,1,0))
plots ...
title("Big Array", outer=TRUE)

You need to set up an outer margin.  See 'An Introduction to R' for that
topic.

You probably want to reset the margins (mar=) for such a large array of 
plots.
