[R] [FORGED] [FORGED] lattice: control panel extent on device

Hi,
I had not noticed the difference, but now that I can see them side-by-side it's obvious. I see that I shouldn't have taken out those modifications you had originally set up. They were sort of like extra those extra parts you find after assembling a new gizmo - "Nah, I don't need those things." Oops!
I just realized that I was calling the alignment vertical (because the plots are over-under), but you referred to the alignment as horizontal which sounds 'righter'. I should challenge myself to do the same for vertical alignment for side-by-side plots. If I get to it I'll post the results.
Thanks, again, for your time and help.
Cheers,
Ben
