Here are two possibilities. The first use trellis.focus/trellis/unfocus to add text subsequent to drawing the xyplot and the second uses a custom panel:
xyplot(x ~ x, data = data.frame(x = 1:10)) trellis.focus("panel", 1, 1) panel.text(x=2, y=4, labels="Text") trellis.unfocus() xyplot(x ~ x, data = data.frame(x = 1:10), panel = function(...) { panel.xyplot(...) panel.text(x=2, y=4, labels="Text") }) On 9/29/06, McGehee, Robert <[EMAIL PROTECTED]> wrote: > Hello, > I've decided to take the leap and try my hand at the lattice package, > though I am getting stuck at what one might consider a trivial problem, > plotting text at a point in a graph.
