Is there an alternative to par(mfrow=c(2,1)) to get stacked scatterplot
matrixes generated with "pairs"?

I am using version 2.11.1 on Windows XP.  The logic I am using follows, and
the second "pairs" plot replaces the first plot in the current graphics
device, which is not what I expected (or desired).

par(mfrow=c(2,1))
pairs(b2007, main="6/2000 - 12/2006")
pairs(a2007, main="1/2007 - 06/2009")

Thanks in advance!

Mike
