[R] Split plot panel into rows with different columns

[Jim Lemon]

Hi Luigi,
Bert has identified the problem. If the ordinates in each row are the
same, you can save quite a bit of space by setting the left and right
margins to zero on all but the left plots in each row. This will jam
the plots together at the sides, but that may not matter to you.
Remember that you have to set the margins for each plot. If you do
this, it is usually better looking if you specify more room for the
leftmost panels.
