r - 如何更改/添加标签到条形图填充 + 如何在条形图内部或外部显示数字？

Question

relationship_bw_Polattrev_fbse_plot<-ggplot(data = anes_sm, aes(x= polattrev_recoded,  fill=fbse_recoded)) +
  geom_bar(position="dodge") +
  labs(x = 'How often do you pay attention to what’s going on in government and politics?',
       y= 'Frequency',
       title = 'Relationship between attention to politics and government and if sees politics online')+
  theme_bw()
relationship_bw_Polattrev_fbse_plot

我想更改我的标签：fill= variable 另外，如何将数字添加到各个条形？
