How to navigate in layout() created graph?

Hi

I created a complex layout with using layout() and it looks exactly as
I need it. But I don't want to print in the order in which the
subfigure are numbered, but in a different order.

How can I navigate in the layout so that I can specify the subfigure
in which to plot?

At the moment I am using a function which is converting the number to
mfg parameter for par, but it does not seem to work as expected.

Thanks,

Rainer
