Dear R users,
I'm using xyplot to obtain a graph about a correlation x~y for different years (a categoric variable).
The program dispose automatically the graphs in this way:

2010
2007 2008 2009
2004 2005 2006 
2001 2002 2003 
1998 1999 2000

Which code should I use to obtain this sequance of graphs?

1998 1999 2000 2001 2002 2003 2004 2005 2006  2007 2008 2009 2010


I have tried with "par" code but it's doesn't work.

Thanks for help,

Francesco Nutini
