One more small improvement:
library(gridExtra)
pgfun <- function(mark) function(n) grid.text(label = mark,
x = unit(0.1, "npc"), y = unit(0.9, "npc"))
fo <- demand ~ Time
grid.arrange(nrow = 2,
xyplot(fo, BOD, page = pgfun("A")),
xyplot(fo, BOD, page = pgfun("B")),
xyplot(fo, BOD, page = pgfun("C"))
)
