hi peter and david,thanks for the excellent suggestions. here is something like what i am finally using (those fancy fonts were really tempting, but i chose something a little more mundane!): library(lattice) x<- sort(rnorm(100,50,10)) y<- sort(runif(100,0,20)) d<- expand.grid(x=x, y=y) d$z<- x + y plot.new() p = levelplot(z ~ x*y, d, par.settings=list( layout.widths=list(right.padding=4)), colorkey = TRUE) print(p) mtext("CAPTION", 4, 1)
Even if that worked (it doesn't for me), you're still mixing base (or tradtional) graphics with lattice graphics. Not a good idea. I would replace the plot.new call with trellis.device() and then, after the levelplot, replace the mtext with grid.text(...) as I suggested originally. You'll have to fiddle a bit with the x location but that should be easy to get the way you want. One more thing, since you imply that this is for publication, it's a good idea to create the plot close to the size that will ultimately be printed; resizing is always better avoided. Peter Ehlers
your help really appreciated! best regards, andrew.
