Here's one solution.
xyplot(flat(d) + linear(d) + logistic(d) +
umbrella(d) + emax(d) + sigmoid(d) ~ d,
data = list(d = seq(0, 8, length = 101)),
ylab='Expected change from baseline in VAS at Week 6', xlab='Dose',
type = "l", outer = TRUE,
strip = strip.custom(factor.levels =
c("FLAT", "LINEAR", "LOGISTIC", "UMBRELLA", "EMAX", "SIGMOID")))
