[R] Spacing Between Elements in Lattice Legend

[Lorenzo Isella]

Dear All,
Please consider the short code at the end of the email.
It generates a barchart where everything is as I want, apart from some
minor tuning of the legend.
I can control the spacing between the text in the two rows of the
legend, but how do I force some separation between the red and the
blue rectangles in the legend?
Any suggestion is welcome.
Cheers

Lorenzo
