Bar graph ggplot in R

Question

I would like to know how to remove these letters a that appear in the bar chart caption in ggplot in R. I want you to have the bar values the same way it appears in the image, but when I run the code, these a appear automatically in the caption.

Code:

CS = data.frame(
  Setores = factor(c("Comércio","Comércio","Serviços","Serviços")),
  Situação = factor(c("Admitidos","Desligados","Admitidos","Desligados"), 
                    levels=c("Admitidos","Desligados")),
  Quantidade = c(2604, -1766, 6826, -5331)

)

ggplot(data=CS, aes(x=Situação, y=Quantidade, fill=Setores)) +
  geom_bar(aes(fill = Setores), stat="identity", position="dodge") +
  geom_label(aes(label =round(Quantidade,0), group = Setores),
             colour = "black", position = position_dodge(width=1))

Answer 1

Just put the argument show.legend = FALSE within the function geom_label:

ggplot(data=CS, aes(x=Situação, y=Quantidade, fill=Setores)) +
  geom_bar(aes(fill = Setores), stat="identity", position="dodge") +
  geom_label(aes(label =round(Quantidade,0), group = Setores),
             colour = "black", position = position_dodge(width=1),
             show.legend = FALSE)
