There is no easy way, especially if you want a general solution, but
for your specific example, here is a possible starting point:
dotplot(variety ~ yield | site * year, data = barley,
subset = (site %in% c("Grand Rapids", "Duluth")),
strip = function(which.given, which.panel,
var.name, factor.levels, ...) {
str(list(which.given = which.given,
which.panel = which.panel,
var.name = var.name,
factor.levels = factor.levels, ...))
if (which.given == 1)
strip.default(which.given = which.given,
which.panel = which.panel,
var.name = var.name,
factor.levels = factor.levels, ...)
else {
panel.rect(0, 0.5, 1, 1, col = "#ccffcc",
border = "transparent")
if (which.panel[1] == 2)
panel.text(0, 0.75,
labels = factor.levels[which.panel[2]])
}
})
