R help - Oct 2010 - lattice key subtitle

Hello everybody,
Is there a way to add a subtitle to a lattice key?
It is important form me that the subtitle must be linked to the key
because those graphs are produced on a daily temporal scale,
and the numbers of  rectangles from the key may be different from day to
day.

Thank you,
Alexandru Dumitrescu

None specifically for that purpose, but latticeExtra does have a
mergedTrellisLegendGrob() function that may help:

mylegend <-
mergedTrellisLegendGrob(list(fun = draw.key,
                             args = list(key = simpleKey(month.name[1:3],
                                                         title =
"Months"))),
                        list(fun = grid::textGrob,
                             args = list("subtitle")),
                        vertical = TRUE)

xyplot(1 ~ 1,
       legend = list(top = list(fun = mylegend)))

mergedTrellisLegendGrob() was written as a helper function for
c.trellis(), but the plan is to eventually make it a bit more general
tool for combining legends.
