To make a long story short, you are right, I need to do this because
my knowledge with trellis graphics is not enough for creating all the
plots at once. However, In this moment I have no time for change the
whole function that produces several spplot graphics (sp package), but
I'll do it in the future.

Thanks anyway,

Mauricio
