Specify position of geom_text by keywords like “top”, “bottom”, “left”, “right”, “center”

Question

I wish to position text in a ggplot without specifying x and y positions, but instead using keywords, like e.g. in graphics::leg

Answer 1

geom_text wants to plot labels based on your data set. It sounds like you're looking to add a single piece of text to your plot, in which case, annotate is the better option. To force the label to appear in the same position regardless of the units in the plot, you can take advantage of Inf values:

sp <- ggplot(mpg, aes(hwy, cty, label = "sometext"))+
  geom_point() +
  annotate(geom = 'text', label = 'sometext', x = -Inf, y = Inf, hjust = 0, vjust = 1)
print(sp)
