Annotate ggplot bar plot in R

Question

How can I annotate the following plot? I want to include counts on top of each bar.

g <- ggplot(mpg, aes(class))
# Number of cars in each class:
g + geom_bar()

I only know how to do it if I do a group by and create a new column 'count' for example.

You can do:

ggplot(mpg, aes(class)) + 
  geom_bar() +
  geom_text(stat = "count", aes(label = after_stat(count)), nudge_y = 1)

Thank you! How can I put the labels a little higher?

Adjust the nudge_y however you please @Eisen

I used the position argument with position_dodge() instead. I'm having trouble however with reordering. It seems I can't reorder by stat = 'count'? Do you know how I can get around this?

Do you have multiple groups at each x position, or are you just reordering the x axis?

Eisen Over a year ago

reordering x axis!
