R help - Jun 2005 - Lattice xyplot -- footnote font size / mtext

Is there a way of controlling the font size and alignment of a footnote
in an xyplot, or alternatively of using 'mtext' to place a footnote at
the bottom of a graph?

Great!  That should do it.  Thanks.

Your best bet is using 'page', e.g.

library(grid)
library(lattice)
xyplot(1 ~ 1, 
       page = function(n) 
           grid.text(paste("footnote for page", n), 
                     x = .99, y = 0.01, 
                     default.units = "npc", 
                     just = c("right", "bottom")))

You could also use panel.text instead of grid.text, but the latter is
more flexible. You could make the font smaller by adding the following
in the grid.text call:

gp = gpar(fontsize = 8)
