is there an comfortable way to set the legend/key label inside the rectanlge in latice plots: (although overplot/overlayer lines, points, rectangles in keys would be nice)
library(lattice)
barchart(yield ~ variety | site, data = barley,
groups = year, layout = c(1,6), stack = TRUE,
auto.key = list(space = "right"),
ylab = "Barley Yield (bushels/acre)",
scales = list(x = list(rot = 45)))
