lattice key subtitle

Hello everybody,
Is there a way to add a subtitle to a lattice key?

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.

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,
