I am not seeing an immediately evident way of doing that.
Bear in mind that pairs() is essentially a wrapper to automate the process of
using par(mfrow = c(rows, columns)) and setting other graphical parameters such
as margins, which sets up the grid of individual plots within the overall
graphic.
You could fairly easily create your own function to do this, which then enables
more flexible customization.
See ?par for more information on 'mfrow' and perhaps also ?layout which
provides another means of creating a matrix of of plots.
