remove legend title in ggplot

Question

I\'m trying to remove the title of a legend in ggplot2:

df <- data.frame(
  g = rep(letters[1:2], 5),
  x = rnorm(10),
  y = rnorm(10)
)

lib         


        

Answer 1

Since you may have more than one legends in a plot, a way to selectively remove just one of the titles without leaving an empty space is to set the name argument of the scale_ function to NULL, i.e.

scale_fill_discrete(name = NULL)
