[R] Annotate question

[Rui Barradas]

Hello,

If groups are factors, pass the level you want to annotate.
This works, note the 'x' value:

ggplot(iris, aes(Species, Petal.Length)) +
   geom_boxplot() +
   annotate(geom = "text", x = "versicolor", y = 6, label = "16 u")


Hope this helps,

Rui Barradas
